I’ve been stuck on this for 3 hours and got 4 different answers...

Question: Find the exterior perimeter of the shape below. (hint: do not count the line in the middle of the shape)

Step-by-step explanation:

The sides for the square are equal to 2x-5 because that is the square root of the area.  The length of the rectangle is 3x+6 and the width is 3x-6 because that is what you get when you factor the equation.

Now, you have add them up.

To take out the line in the middle of the shape we will subtract because we are assuming that this equation is equal to the shorter side.  This makes the equation

If you are looking for a numerical answer, I can't say I know how to get it.

Hope this helps! <3

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
