Answer:
17
Step-by-step explanation:
We are given the expression find x + 9 if x = 8.
When a certain number has a variable and the value of the variable is known, all you have to do is plug in the variable amount into the equation, therefore :
x is 8 , so we plug in 8 for x
x + 9 =
8 + 9 = 17
D. y = 9 because it has a complete zero slope while the y-intercept of the equation is 9, so the equation is y = 9.
The surface area in this equation is 5x4 which is 20
I think the answer is b and c but I’m not very sure
