Question D- If the area of a square is 121 square centimeters, what is its side length?

1 answer:

3 0

The formula for the area of a square is the side squared, or multiplied together.

Basically, if the side length is x, the area is x*x or x^2.

We can use that to set up an equation.

x^2=121
x=square root of 121=11

Hope this helps!

-15 -3 3 15 Pls help idk this

kykrilka [37]

Answer:

-3

Step-by-step explanation:

4^x = (1/8)^(x+5)

(2^2)^x = (2^-3)^(x+5)

2^2x = 2^(-3x - 15)

Since both sides have the same base of 2, then the exponents are equal

2x = - 3x - 15

5x = -15

x = -3
