1) (12²)³ ₓ 12⁻⁴ = multiply exponents when you raise an exponent to an exp.
   12⁶ ₓ 12⁻⁴ = add
   12²

2) (12⁷ ₓ 12⁻⁵) / 12² = add the exponents up top
   12² / 12² = move all numbers to numerator and change signs
   12² ₓ 12⁻² = add the exponents
1

What is the volume of this entire prism

lisabon 2012 [21]

Answer:

520 cubic centimeters (cm^3)

Step-by-step explanation:

volume = length * width * height

length = 13

width = 5

height = 4 + 4, so height = 8

volume = (13) * (5) * (8)

volume = 520 units

Since the given measurements are in centimeters and the answer is the volume of the prism, the answer must be in cubic centimeters

So, the final answer is 520 cubic centimeters (cm^3)

13. What are the x-intercepts of<br> y = 2x2 + 6x - 20?

Brilliant_brown [7]

Answer:

x = -5, 2

Step-by-step explanation:

The first step to factor the equation is removing any factors/like terms that all of the variables share.

In the equation $y = 2x^2+6x-20$ , all numbers are multiples of 2, therefore you can factor out 2 from to equation

$y = 2(\frac{2x^2}{2} + \frac{6x}{2} -\frac{20}{2})$

$y = 2(x^2+3x-10)$

Next, you can factor the equation in the parenthesis. Since x^2 is not multiplied by anything, you know that the factors of x^2 must be x and x. Therefore, the two factors of -10 must add up to 3. The only two factors of -10/x that add up to 3 are 5 * -2.

The factors of the equation are then (2)(x+5)(x-2)

Lastly, set up only the factors containing a x to 0 in order to solve for x-intercept.

x+5 = 0; x= 0-5 ; x = -5

x - 2 = 0; x = 0 + 2; x = 2
