Answer:
3.65 ≤ x < 3.75
Step-by-step explanation:
We are finding the lower and upper bounds:
The lowest possible number that can be rounded to 3.7 is 3.65 as the 5 makes the 6 go next.
The maximum possible number to 2 d.p that will be 3.74 as the 4 keeps it at 3.7.
But someone can say 3.749 is a bigger number that 3.74 that will get rounded to 3.7
Someone else can argue with 3.7499.
So to solve this argumnet we put 3.75 but we don't include it.
Therefore our final answer is :
3.65 ≤ x < 3.75
Hope this helped and branliest please.
Two angles (angle C and angle D) are
supplementary. The measure of angle C is
5x – 6 and the measure of angle D is 7x +
14. Find the measure in degrees of each
angle
Answer:
C= 65.5°
D= 114.1°
Step-by-step explanation:
5x - 6 + 7x +14 = 180
5x + 7x + 14 - 6 = 180
12x + 8 = 180
- 8 - 8
12x = 180
12x/12 = 180/12
x = 14.3
C= 5x - 6
5(14.3)-6
71.5 - 6
C=65.5°
D= 7x + 14
7(14.3) + 14
100.1 + 14
D= 114.1°
65.5 + 114.1 = 179.6°
When this is rounded up, you will get 180°
Hope this helps!

Answer:
Your answer Exterior C is 160°
Interior C is 20°
Step-by-step explanation:
<A + <B + <C = 180°
<Left C + <Right C = 180°
<A + <B = <Right C
(5x - 10)° + 12x° = 16x
17x - 10 = 16x
x = 10
<A = 5x - 10
<A = 5*10 - 10
<A = 50 - 10 = 40°
<B = 12x
<B = 12*10
<B = 120°
<A + <B = <Right C.
40° + 120° = 160°

5/root of 7 - 2 is rationalized by multiplying the numerator and denominator by what?
The considered fraction is ationalized by multiplying the numerator and denominator by the expression as given by: Option A: √7 + 2
How to rationalize a fraction?Suppose the given fraction is [tex]\dfrac{a}{b+c}[/tex]
Then the conjugate of the denominator is given by b - c
Thus, rationalizing the fraction will give us
[tex]\dfrac{a}{b+c} \times \dfrac{b-c}{b-c} = \dfrac{a(b-c)}{b^2 - c^2}[/tex]
(we used the identity [tex](b-c)(b+c) = b^2 - c^2[/tex])
We actually rationalize just for the use of that later denominator or numerator(if they seem to be helpful).
Remember that
[tex]\dfrac{b-c}{b-c} = 1[/tex]
thus, multiplying it with the fraction doesn't change its value, and just change the way how it looks. We assume that b-c is not 0
For this case, the given fraction is:
[tex]\dfrac{5}{\sqrt{7} - 2}[/tex]
Thus, here we will multiply the denominator with [tex]\sqrt{7} + 2[/tex] so that we can use the identity [tex](b-c)(b+c) = b^2 - c^2[/tex].
Thus, we get:
[tex]\dfrac{5}{\sqrt{7} - 2} \times \dfrac{\sqrt{7} + 2}{\sqrt{7} + 2} = \dfrac{5(\sqrt{7} + 2)}{(\sqrt{7})^2 - 2^2} = \dfrac{5(\sqrt{7} + 2)}{3}[/tex]
See, the denominator now looks a bit better. We try to make it look smooth and simplified because division is more complex than multiplication, so its better to have square root term in numerator than in denominator.
Thus, the considered fraction is ationalized by multiplying the numerator and denominator by the expression as given by: Option A: √7 + 2

a rectangle has an area of 72 square inches and a width of 9 inches what is its perimeter?
Answer:
34 inches.
Step-by-step explanation:
In order to ger perimeter you need to find the value of all sides. We know one side is 9 inches. To find the other side length you divide the area by the side length (72/9=8). This is because the formula for area is length times width. To find permiter you add all the side lengths together. A rectangle has 4 sides, so you would do 9+9+8+8

The solution is, x_1 = -2 + 2√3 and, x_2 = -2 - 2√3, are solutions to the equation below.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
1) Since we've been given the equation x²+4x +4=12 then let's solve it to find the roots
2) Applying the resolutive formula
x²+4x +4=12
x²+4x +4-12 =0
x²+4x -8=0
now, we know, here,
D = b² - 4ac
so, solving we get,
D = 48
Now, the roots are,
x = -b ± √D / 2a
so, here, we get,
x_1 = -2 + 2√3
x_2 = -2 - 2√3
