Hi there!

To solve, we must use PEMDAS:
P: Parenthesis
E: Exponents
M: Multiply
D: Divide
A: Add
S: Subtract
Evaluate the inside of the parenthesis:
(124 + 6 × 8)
Multiply first:
(124 + 48)
Evaluate:
124 + 48 = 172
Divide by 2:
172 ÷ 2 = 86 = t
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
Answer:
1.91/9
Step-by-step explanation:
x=0.212121212........ .........1 equation
10x=2.12121212......... ........2 equation
1 equation - 2 equation
9x=1.91
x=1.91/9
therefore 0.212121.....=1.91/9
