Ok so the equation is 5²-(5-7)×2
first we need to take care of the parenthasis
5²-(-2)×2
and then the exponents
25-(-2)×2
then the multiplication
25-(-4)
29 is your final answer
I hope I've helped!

Perimeter is adding the 3 sides together. Since both triangles have the same perimeter set both triangles to equal:
(x+3 + x+3 + x+3) = (x+3 + 2x-3 + x)
Simplify each side:
3x+9 = 4x
Subtract 3x from each side:
x=9
14=-2(2x+1)
14=-4x-2
+2. +2
16=-4x
