Answer:
2 is your answer.
Step-by-step explanation:
Simplify. Remember to follow PEMDAS. First solve the parenthesis, then multiply, and finally divide.
-8(17 - 12) = -8(5) = -40
-2(8 - (-2)) = -2(8 + 2) = -2(10) = -20
-40/-20 = 2
2 is your answer.

Answer:
CSA of cylinder = 704cm²
We know that
CSA of cylinder = 2πrh
or 2πrh = 704
or, 2*22/7 *8 *h = 704 ( since r=8cm)
or, 352h = 704*7
or, h = 4928/352 = 14cm
(7-11) • (5) = -20
A. (5) • 7 + (5) • (-11)
↳ 35 + (-55)
↳ 35 - 55 = -20
B. -(-7+11) • (5)
↳ -4 • 5 = -20
C. (5) • 7 - (5) • 11
↳ 35 - 55 = -20
D. (7+11) • (5)
↳ 18 • 5 = 90
A B & C are correct
