Answer:
I think it’s step 2 where she distributed the exponents incorrectly but she got it right so since no explanation is really needed then I guess it’s step 2.
step 1 where she divided 5 on both sides. Step 3 is also correct since the answer is 0. so step 2 had the mistake.
The length of side of triangle is 5 units and length of side of pentagon is 1.5 units.
<u>SOLUTION:</u>
Given, An equilateral triangle has sides of length
units.
Then, perimeter of the triangle will be 
A regular pentagon (5 sides) has sides of
units.
Then, perimeter of the pentagon will be 
We have to find the dimensions of each shape
. Now, the perimeter of the triangle is twice the perimeter of the pentagon,
So, 

Then, length of side of triangle
Length of side of pentagon
We have to neglect, negative sign as lengths can’t be negative. Even if we change the sign above all conditions are satisfied.
