-(5 n + 6)
Step-by-step explanation:
Simplify the following:
-4 (n + 1) - (n + 2)
-4 (n + 1) = -4 n - 4:
-4 n - 4 - (n + 2)
-(n + 2) = -n - 2:
-4 - 4 n + -n - 2
Grouping like terms, -4 - 4 n - 2 - n = (-4 n - n) + (-4 - 2):
(-4 n - n) + (-4 - 2)
-4 n - n = -5 n:
-5 n + (-4 - 2)
-4 - 2 = -(4 + 2):
-5 n + -(4 + 2)
4 + 2 = 6:
-5 n - 6
Factor -1 out of -5 n - 6:

18.8 cubic inches.
step-by-step explanation:
volume of a cone = πr²h
r = 1.5 inches
h = 8 inches
pi = 3.14
volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches
or equals to 18.8 square inches rounded up to nearest tenth.
