Answer:
B
Step-by-step explanation:
A. 8 * x = 80
8 * 5 = 40. 40 is not 80, so it doesn't work.
B. x + 4 = 9
5 + 4 = 9. This works.
C. 10 ÷ x = 5
10 ÷ 5 = 2. 5 is not 2, so it doesn't work.
D. x - 6 = 1
5 - 6 = -1. 1 is not -1, so it doesn't work.

f(3)=21
Cylinder is 10 meters wide, so its diameter is 10 meters. You get radius of it by dividing 10 by 2, which equals 5.
As you count volume of cylinder from that equation
You get an equation to count height:
h≈3.82 meters
(X+7)(x+4). 7 times 4 equals 28 while also equaling 11 when added. You use the Foil Method to check you answer (First, Outer, Inner, Last).
Base six and greater would make 4025 a legitimate numeral.
