5x-10=2x+5
We simplify the equation to the form, which is simple to understand
5x-10=2x+5
We move all terms containing x to the left and all other terms to the right.
+5x-2x=+5+10
We simplify left and right side of the equation.
+3x=+15
We divide both sides of the equation by 3 to get x.
x=5

Answer:
(assuming you are knowledge about Pythagoras theorem)
44.205
Step-by-step explanation:
draw the altitude line to the upper right corner and the lower left corner and you have 2 identical right triangles and a rectangle. If you solve the third side of the right triangles you get 1.685 (sqrt[7.2^2 - 7^2]).
now add up the areas of both triangles and the rectangle in the center whose base is 4.63 (subtract the 3rd side from 8)
you have
1.685(7) + 7(4.63)
Answer: the area for the square is 126.56cm²:
32yd is longer as 32yd is equivalent to 96ft
