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!

What are zeros of f(x)=x^2-3x-18. and please explain so I can see if I can understand.

Daniel [21]

F(x) = x^2 - 3x - 18

Find the values that when multiplied equal -18 and when added equal -3 (6 and -3)
Plug it into f(x) = (x - 1st value)(x - 2nd value)

f(x) = (x - 6)(x + 3)
0 = (x - 6) (x + 3)

(One of the factors has to equal zero, so set them both equal to zero)

x - 6 = 0
x = 6

x + 3 = 0
x = -3

x = 6, x = -3
