Answer:
x = 3.6
B. {7.88}
Step-by-step explanation:

x · 10 = 6 · 6
10x = 36
10x ÷ 10 = 36 ÷ 10
x = 3.6

8 · x = 9 · 7
8x = 63
8x ÷ 8 = 63 ÷ 8
or x = 7.875
7.875 rounded to the nearest tenth is 7.88.
Answer:
-9
Step-by-step explanation:
100 x -.09 = -9 (move the decimal over two places to the right because you are multiplying by 100)
Surface area = 2 pi (3x-2)^2 + 2 pi (3x -2) ( x + 3)
= 2 pi (9x^2 - 12x + 4 + 3x^2 + 7x - 6
= 2pi(12x^2 - 5x - 2)
