Answer:
SA = 384 in²
Step-by-step explanation:
Assuming we're finding surface area:
SA of top of large cube: 8(8) - 4(4) = 48 in²
SA of sides of large cube: 4(8)(8) = 256 in²
SA of exposed faces of small cube: 5(4)(4) = 80 in²
Total = 48 + 256 + 80 = 384 = ∑SA
Answer:

Step-by-step explanation:
Given expression,

=>
We see that
is common in both numerator and denominator
hence canceling out we get:-

Answer=
Answer:
Step-by-step explanation:
7(x-5)²=63
(x-5)²=63/7
(x-5) = +/- 3
x = 5 + 3
or
x = 5- 3
x = 8 or 2
3 1/2
x365
Write that down and figrue it its pretty simple.
