Step-by-step explanation:
I used my calculator, so they should be correct.
Answer:
First Box: Factor by difference of squares
Second Box: It has all perfect squares
Third Box: see my work
Step-by-step explanation:
We have the equation ![4x^2=36](https://tex.z-dn.net/?f=4x%5E2%3D36)
Before we do anything, let us bring all of the terms to the left side
![4x^2-36=0](https://tex.z-dn.net/?f=4x%5E2-36%3D0)
Now that we have moved the terms to one side, it is clear that we have a difference of squares.

Answer:mr clark
Step-by-step explanation:
4%n = 5
Simplify the equation
1/25n = 5
Multiply by 25
25 (1/25n) = (25) (5)
n = 125.
