Answer:
2x + 4
Step-by-step explanation:
Let R = Ralph's age
and x = Sarah's age
Then Ralph's age in 4 years = R + 4
and Sarah's age in four years = x + 4
Thus, R + 4 = 2(x + 4)
Distribute the 2 R + 4 = 2x + 8
Subtract 4 from each side R = 2x + 4
Ralph's age is 2x + 4.
The question is asking the lateral surface area of a cylinder with radius 3 in and length 12 in.
A = 2πr*l
.. = 2π*(3 in)*(12 in)
.. = 72π in^2
.. ≈ 226 in^2 . . . . . . . . . . matches selection a)
Answer is 16 because 16/4 = 4 + -12 = -8
