Answer:
n=45/2
or
n=22.5
or
22 1/2
Step-by-step explanation:
Answer:1,150 pennies
Step-by-step explanation:four times five is 20
.75 is three parts of one hundred so you do 23 times 50 and get 1,150
Angle 15 and Angle 9 make a straight line
Answer:
V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)
Step-by-step explanation:
The volume of a rectangular prism of length L, depth W and height H is
V = L * W * H.
Thus,
in this case,
V = (2x + 1)(x - 2)(3x).
The order in which we multiply these quantities together is immaterial.
Working from left to right, we get:
V = (2x^2 - 3x - 2)(3x), and then:
V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)
