How do I solve this? (please help to find what goes in the boxes as well)

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 $4x^2=36$

Before we do anything, let us bring all of the terms to the left side

$4x^2-36=0$

Now that we have moved the terms to one side, it is clear that we have a difference of squares.

-Work-

$4x^2=36\\\\4x^2-36=0\\\\(2x+6)(2x-6)=0\\\\$

$2x+6=0\\\\2x=-6\\\\x=-3$

$2x-6=0\\\\2x=6\\\\x=3$

A parachutist's rate during a free fall reaches 198 feet per second. What is this rate in meters per second? At this rate, how m

amm1812

Answer:

300 feet

Step-by-step explanation:

If we were using feet the expression would be 198x, where x is feet per second

Since they are asking in meters we need to convert feet to meters

When you do that you get 60

Now the expression is 60x

When you plug 5 into the equation it is 300
