Answer:

x^2+12x-13 = 0

Step-by-step explanation:

12x=13-x^2

=>12x+x^2=13-x^2+x^2

=>x^2+12x-13 = 13-13

=> x^2+12x-13 = 0

Answer:

x² + 12x - 13 = 0

Step-by-step explanation:

12x = 13 - x²

the standard form of an equation is written starting from the variable of the highest degree to the lowest. Hence after rearranging;

0 = 13 - x² - 12x

0 = -x² - 12x + 13

In an equation, the highest degree of a variable should preferably be postive hence the equation to the left side to remove the negative sign:

x² + 12x - 13 = 0

Answer:

0

Step-by-step explanation:

-4 times -6x is 24x and-4 x -3 = 12

isolating 24x on the right side we subtract twelve on the right and on the left to get 24x=0 and 24 divided by zero is 0

Answer:

[tex]75.4 in^3[/tex]

Step-by-step explanation:

First start with your cone volume equation which is

[tex]V=\pi r^2\frac{h}{3}[/tex]

Now plug in what you know

r=3

h=8

[tex]V=\pi (3)^2(\frac{8}{3})[/tex]

put in calculator and get

[tex]75.4 in^3[/tex]

Answer:

2x=18

Step-by-step explanation:

2 times 9 equals 18 and if they both have 18 together the only anwser would be 2x=18 x=9 Another way I could put it to make it more simple is 2X9=18 or 29=18

Answer:

y=2/5(x)-4

Step-by-step explanation:

m=2/5

y=mx+b

2=2/5(15)+b

b=-4

Answer:

m= 2/5 (i don't know if you have to put x)

b= -4

y = 2/5x-4

Answer:

292.75mL

Step-by-step explanation:

From the ideal gas equation

PV= nRT

With each symbols having standard meaning

For pressure remaining constant the equation for two states can be written as

[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]

Given V_1 = 300mL, T_1 = 17° C = 290K and T_2 = 10°C or 283K

Now plugging values in above equation to find V_2

[tex]\frac{300}{290} =\frac{V_2}{283}\\V_2 =\frac{300}{290}\times283 = 292.75mL[/tex]

Therefore, the volume at 10 degrees Celsius = 292.75mL

Answer:

A 0.4kg object rolling at 2 m/s that's d right answer

Answer:

A 0.4 kg object moving at 4 m.

Step-by-step explanation:

The heavier the object is, the faster it goes. Also the faster is goes and the heavier it is, the more momentum it has.

Answer:

f(x) = x^3 + 2x^2 + x + 2

Step-by-step explanation:

If -2 + i is a zero, then -2 - i must also be a zero.

These zeros are -2, -2 + i and -2 - i, and the corresponding factors of the polynomail f(x) are (x + 2), (x + 2 - i) and (x + 2 + i).

(x + 2 - i) and (x + 2 + i) multiplied together becomes x^2 + 1.

Multiplying this result by the 3rd and last factor, (x + 2), we get

(x^2 + 1)(x + 2) = x^3 + 2x^2 + x + 2

Check, using synthetic division.  What are the factors of x^3 + 2x^2 + x + 2?

-2   /   1    2    1    2  

              -2   -2   -2

     -----------------------

         1      0    -1    0                  Since the remainder is zero, we know that

                                                    (x + 2) is a factor and -2 is a root.

Answer:

Optimisation Problem

Explanation:

Optimisation Problem is a mathematical economics, computer science problem - which finds the best solution from all feasible solutions (based on constraints & other aspects).

The problem might be in form of maximisation or minimisation. The bus system designing is based on minimizing walking distance. Thus is an optimisation problem.

Answer:

#1 is Geometric

the common ratio is 2

#2 is Arithmetic

the common difference is 6

Answer:

(17)

Sum of interior angles of a quadrilateral is 360°

(18)

Sum of interior angles of a hexagon is 180°*(6 - 2) = 720°

(19)

Interior angles of a given pentagon are all marked as congruent, so the exterior angles are congruent too.

Sum of exterior angles is 360°.

Answer:

there are 18 cubes in that box.

Answer:

12m + 24

Step-by-step explanation:

Using the distributive property, distribute 6 to the terms in the parentheses

6(2m + 4)

12m + 24

So, the equivalent expression is 12m + 24

Answer:

I think you wrote something wrong.

Step-by-step explanation:

If Alaina has $7 in her bank account and Joel had $48 in his Joel already has more then Alaina but I will attempt to teach you how to solve these types of problems.

for this example I'm giving Alaina 79 dollars.

First we know were starting with 79 dollars and increasing 6 dollars each day so the equation for this is; y = 6x + 79 that is Alaina's equation.

For Joel our equation will be; y = 8x + 48.

Since they already have 79 and 48 dollars in their bank we put those as our B in the equation cause they are our y-intercepts. (Y = mx + b) Next we know their increasing by 6 and 8 dollars a day so we make those our m. Once we have these equations we can plot them and see where the lines meet. (thats our answer) I plotted them on desmos graphing calculator.

They crossed at (15.5, 172) Which means it will take 16 days for Joel to catch up they will both have 172 dollars in the bank account on the 16th day.

Hope this helps!
