Answer:
Step-by-step explanation:
Let 'a' and 'e' represent Alvin's and Elga's ages, respectively.
a = e-12 . . . . . Alvin is 12 years younger
a + e = 86 . . . the sum of their ages is 86
__
Substituting for 'a' gives ...
(e -12) +e = 86
2e = 98
e = 49
a = 49 -12 = 37
Alvin is 37; Elga is 49.
Answer:
15 inches.
Step-by-step explanation:
V = 1/3 pi r^2 h
7065 = 1/3 * 3.14 * 30 * r^2
r^2 = 7065 / (1/3 * 3.14 * 30)
r^2 = 7065 / 31.4 = 225
r = sqrt 225 = 15.
The final expression is 
Step-by-step explanation:
The expression that we have is

In order to solve the expression, we start by applying the distributive property to the bracket. We get:

Simplifying,

Now we add the two terms in x, and we find:

Which is the final expression.
