If using the method of completing the square to solve the quadratic equation x^2+8x-4=0 which number would have to be added to "complete the square"?
I need the answer ASAP. Please help. Thank you
x^2 + 8x - 4 = 0
(x^2 + 8x + 8/2^2) - 4 - 8/2^2 = 0
(x^2 + 8x + 16) - 4 - 16 = 0
(x^2 + 8x + 16) - 20 = 0
(x + 4)(x + 4) - 20 = 0
The number that is to be added to complete the square is 8/2^2, or 16.
A cube has a surface area of 600 square meters. What is its volume?
A.600 m³
B.300 m³
C.100 m³
D.1000 m³
Answer: D, 1000 m^3.
Step-by-step explanation: We can find the volume by breaking down the surface area.
The formula for the surface area of a cube is 6*x^2 with x being the side length and 6 being the number of sides. Thus we can form the equation as follows:
600 = 6*x^2 - original equation
x^2 = 100 - divide both sides by 6
x = 10 - square root both sides
Thus, the side length is 10.
We can find the volume with the formula l*w*h or, in this case, x^3.
We know that x = 10, so x^3 must be 1000.
Thus, the answer is D, 1000 m^3.

Cara and marcus shared a candy bar. The models are shaded to show the fraction of the candy bar each of them ate. What fraction of the candy bar did Cara and Marcus eat altogether?
Answer:
A. 11/12
Step-by-step explanation:
A. 11/12
B. 9/16
C. 1/12
D. 9/24
Cara = 8/12 candy bars
Marcus = 1/4 candy bars
What fraction of the candy bar did Cara and Marcus eat altogether?
Total candy bars = Cara + Marcus
= 8/12 + 1/4
= 8+3/12
= 11/12 candy bars
The correct answer is A. 11/12

Let x represents a length in cm where x > 1.5.
AB = 2x - 3, BC = 4x – 6,
AD = 2x + 3 and BE = 4x +1
• ABC is right triangle of area Sı.
. CBFG is a rectangle of area S2.
• ADEB is a right trapezoid of area S3.
1) Express S1, S2 and S3 in terms of x.
2) Let S = S1 + S2 -S3.
Answer:
1) S1 = 4·x² - 12·x + 9
S2 = 12·x² - 26·x + 12
S3 = 6·x² - 5·x - 6
2) S = 10·x² - 33·x + 27
Step-by-step explanation:
The length x in cm > 1.5
Segment AB = 2·x - 3, segment BC = 4·x - 6, segment AD = 2·x + 3 and segment BE = 4·x + 1
1) a) The area of the right triangle ABC = S1 = 1/2 × Base × Height
The base of the triangle ABC = Segment BC = 4·x - 6
The height of the triangle ABC = Segment AB = 2·x - 3
Therefore, The area of the triangle ABC = S1 = 1/2 × (4·x - 6) × (2·x - 3) = 1/2 × (8·x² - 12·x - 12·x + 18) = 4·x² - 12·x + 9
S1 = 4·x² - 12·x + 9
b) The area of the rectangle CBFG = S2 = Base × Height
The base of the rectangle CBFG = BC = 4·x - 6
The height of the rectangle CBFG = BF = 3·x - 2
The area of the rectangle CBFG = S2 =(4·x - 6) × (3·x - 2) = 12·x² - 8·x - 18·x + 12
The area of the rectangle CBFG = S2 = 12·x² - 26·x + 12
S2 = 12·x² - 26·x + 12
c) The area of the trapezoid ADEB = S3 = 1/2 × (Long side + Short side) × The height of the trapezoid ADEB
The long side of the trapezoid ADEB = BE = 4·x + 1
The short side of the trapezoid ADEB = AD = 2·x + 3
The height of the trapezoid ADEB = AB = 2·x - 3
The area of the trapezoid ADEB = S3 = 1/2 × (4·x + 1 + 2·x + 3) × (2·x - 3) = 6·x² - 9·x + 4·x - 6
∴ The area of the trapezoid ADEB = S3 = 6·x² - 5·x - 6
S3 = 6·x² - 5·x - 6
2) S = S1 + S2 - S3 = 4·x² - 12·x + 9 + 12·x² - 26·x + 12 - (6·x² - 5·x - 6) = 10·x² - 33·x + 27

Answer:
2×5×11 = 110
Step-by-step explanation:
The factors are separated by the × (multiplication) sign. Common factors are numbers that are factors of both products.
It can be useful to list the factors in order of size, for easier comparison.
1st product:
2 × 3² × 5² × 11 × 17
2nd product:
2 × 5 × 7 × 11² × 13²
Ignoring exponents (for the moment), the numbers that appear in both products are 2, 5, 11. (I've highlighted them so you can see them more easily.)
Now, we consider the exponents. We want to determine the lowest exponent of each of these factors.
2 has the same exponent in both products: 1
5 has exponents of 2 and 1. The least of these is 1.
11 has exponents of 1 and 2. The least of these is 1.
So, the greatest common factor (GCF) is ...
2¹ × 5¹ × 11¹ = 2×5×11 = 110 . . . . greatest common factor
(Comment on answer format: the given numbers are shown as a product of factors. It is not clear whether the desired answer format should match, or should have the value multiplied out. We have shown both ways.)
_____
Check
If we factor out the "greatest common factor," the given products can be written as ...
(2×5×11) × (3² × 5 × 17)
(2×5×11) × (7 × 11 × 13²)
You will notice that the right factors of each of these products have nothing in common. So, we have found the greatest common factor.

Hey there!
Given;
The triangle is a right angled triangle, whose one side is 26 and another side is X. It has also one angle that is 41°.
Now, taking reference angle as angle 41°. We get;
Perpendicular= 26
Base = X
and Reference angle = 41°.
We know that the ratio of tan is p/b. So, let's use this ratio.
[tex] \tan(41°) = \frac{26}{x} [/tex]
[tex]0.869 \times x = 26[/tex]
[tex]x = \frac{26}{0.869} [/tex]
Therefore, The value of x is 29.90.

At the movie theatre, child admission is $5.10 and adult admission is $8.80. On Saturday, 157 tickets were sold for a total sales of $1144.80. How many child tickets were sold that day?
Answer:
64 child tickets
Step-by-step explanation:
Let's set this up a system of equations. Number child tickets is c and adults are a.
5.1c+8.8a=1144.8
c+a=157
We can now solve by elimination. Let's multiply the second equation by -8.8 so that we are left with the child tickets.
-8.8c-8.8a= -1,381.6
We combine the two equations.
-3.7c=-236.8
Divide both sides by -3.7
c=64

Step-by-step explanation:
Credit card A has an APR of 27.2% and an annual fee of $96, while credit card B has an APR of 30.3% and no annual fee. All else being equal, which of these equations can be used to solve the principal P for which the cards offer the same deal over the course of a year
Answer: D. P * (1 + 0.272/12)¹² + 96 = P * (1 + 0.303/12)¹²
Step-by-step explanation:
Credit Card A deal over the course of a year:
Payments are done per month so values need to be converted to monthly figures.
APR per month = 27.2%/12
Period = 1 year * 12 months = 12
= P * (1 + 27.2%/12)¹² + 96
Credit Card B deal over a year
= P * (1 + 30.3%/12)¹²
The Principal that will enable both cards to offer the same deal will therefore be:
P * (1 + 27.2%/12)¹² + 96 = P * (1 + 30.3%/12)¹²

Use the figure below to Find midsegment please help
Answer:
38 units.
Step-by-step explanation:
4x + 6 = [tex]\frac{1}{2}(4x + 44)[/tex] {midpoint theorem}
4x + 6 = [tex]\frac{1}{2}*4x + \frac{1}{2}*44[/tex]
4x + 6 = 2x + 22
4x -2x + 6 = 22
2x + 6 = 22
2x = 22 -6
2x = 16
x = 16/2
x = 8
Length of midsegment = 4x + 6 = 4*8 + 6

9. What is the value to x in the inequality -4(6 + 5x) - 7 < - 9(2x+ 3)
Answer:
x [tex]\geq[/tex] -2
Step-by-step explanation:
Remove parentheses and distribute -4 and -9, calculate the difference, move the variable and constant, collect like terms. ( -2x [tex]\leq[/tex] 4), and divide both sides, and you'll end with -2.
Answer:
x > -2 (last choice)
Step-by-step explanation:
Using the distributive property multiple -4 to both integers
-24 - 20x - 7 < -18x - 27
-31 - 20x < -18x - 27
Add 27 on both sides
-4 - 20x < -18x
Add 20x on both sides
-4 < 2x
Divide each side by 2
x > -2

Answer:
There are [tex]35.74\ cm^2[/tex] of felt left over.
Step-by-step explanation:
The side of the felt square is 8 cm. A circle of radius 3 cm is cut from the square piece of felt.
The portion of felt leftover is the difference between the area of the square and the area of the circle.
The area of the square is:
[tex]A_s=(8\ cm)^2=64\ cm^2[/tex]
The area of the circle is:
[tex]A_c=\pi(3\ cm)^2=3.14*9\ cm^2[/tex]
[tex]A_c=28.26\ cm^2[/tex]
The remaining area of the piece of felt is:
[tex]A=64\ cm^2-28.26\ cm^2[/tex]
[tex]A=35.74\ cm^2[/tex]
There are [tex]35.74\ cm^2[/tex] of felt left over.

Answer:
AY = 16
IY = 9
FG = 30
PA = 24
Step-by-step explanation:
The centroid of the triangle divides each median at the ratio 1: 2 from the base
Let us solve the problem
In Δ AFT
∵ Y is the centroid
∵ AP, TI, and FG are medians
→ By using the rule above
∴ Y divides AP at ratio 1: 2 from the base FT
∴ AY = 2 YP
∵ YP = 8
∴ AY = 2(8)
∴ AY = 16
∵ PA = AY + YP
∴ AP = 16 + 8
∴ AP = 24
∵ Y divides TI at ratio 1: 2 from the base FA
∴ TY = 2 IY
∵ TY = 18
∴ 18 = 2
→ Divide both sides by 2
∴ 9 = IY
∴ IY = 9
∵ Y divides FG at ratio 1:2 from the base AT
∴ FY = 2 YG
∵ FY = 20
∴ 20 = 2 YG
→ Divide both sides by 2
∴ 10 = YG
∴ YG = 10
∵ FG = YG + FY
∴ FG = 10 + 20
∴ FG = 30
