The answer is A) 1/8 or -1/8
Answer:
3
Step-by-step explanation:
tick number 1 and 5. because if 30%=120 , therefore 100%= 100/30*120=400
The answer is
<span>(a−b)²+b²/a²
proof
if A is the area of the
</span><span>inner</span> squared, so A= c², and c²= (a−b)²+b²
so the side of the outer must be a-b +b=a, its area is a²
