Question

The length of a side of a square is 5x + 2 units. If the perimeter is 48, what would the equation be to represent this information?

Answer 1

9.2

Explanation:

5x-2=48

5x+2-2=48-2

5x/5=46/5

=9.2

Answer 2

Hi :)

The formula for finding the perimeter of a square is
`P=4a`, where P=perimeter, a=side length.

We know
`a`, so we plug that into the equation

`P=4(5x+2)`

Now we also know the perimeter, so we plug that into the formula

`48=4(5x+2)`

Or

`4(5x+2)=48`
