Answer:
x = 14
Step-by-step explanation:
The angles form a straight line which makes them add to 180 degrees
4x+ 8x+12 =180
Combine like terms
12x+12 =180
Subtract 12 from each side
12x+12-12 = 180-12
12x=168
Divide each side by 12
12x/12 =168/12
x =14
Answer:
0
Step-by-step explanation:
h(x) = -16x^2 + 32x
Let x= 2
h(2) = -16(2)^2 + 32(2)
= -16(4) +64
=0
(x + 2)/(x + 7) = 3/6
6(x + 2) = 3(x + 7)
6x + 12 = 3x + 21
6x - 3x = 21 - 12
3x = 9
x = 9/3 = 3
