Answer: The equation is 5x = 125
Step-by-step explanation:
A pentagon is a five sided figure so all the side lengths must be equal. And to find the perimeter of a pentagon the you will the five equal side lengths.
So assume we don't know the side lengths so we will represent it by x and the side lengths are 5 so we will have five x's and they will add up to 125 and that could be represent by the equation.
x + x + x + x + x = 125
5x = 125
x = 25
All 3 use a similar equation to find the area
A=bh for <span>parallelograms and rectangles
and A=1/2bh for triangles.
plus a rectangle is a parallelogram with all angles at 90 degrees and a parallelogram can be made up of triangles</span>
To solve this problem you do this:
-first you add 9 to both sides to eliminate the 9
-you then divide by 5 to both sides to get the y by itself
-and your left with y=5
