Answer:
37.5
Step-by-step explanation:the formula of surface area of a square is 6a²
and a is 2.5 in this case,so 6*2.5*2.5=37.5
2(5x^2+2x)+2(3x^2)
10x^2+4x+6x^2
16x^2+4x
D is the correct answer.
The answer is 33 because 40*0.825 or 40*82.5% is 33 men.
Add 35+ 72.5=107.5 that should give you your answer for c and the answer for d is acute because the triangle would have to be 360 to be Obtused and it's not a right triangle because you don't have a 90 degree angle
