Answer:
x= -5/2
Step-by-step explanation:
4 - (2x+4)=5
4-2x-4=5
-2x=5
x=-5/2
Answer:
1017.4 m³
Step-by-step explanation:
Volume of cone V = (1/3)πr²h
pi = 3.14
r = 9 and r² = 81 m²
h = 12 m
V = (1/3)*3.14*81*12
V = 1017.36 rounded 1017.4 m³, which is the first answer.
Answer:
x=12 makes (X-12)/(x-8) equal to zero
x=8 makes (X-12)/(x-8) undefined
Step-by-step explanation:
(x-12)/(x-8) = 0
The first step is to multiply each side by x-8
(x-8) *(x-12)/(x-8) = 0 * (x-8)
This cancels the denominator. x≠ 8 because the denominator would equal 0 and then it becomes undefined.
x-12 = 0
Add 12 to each side
x-12+12 = 0+12
x = 12
