Answer:
D. 34
Step-by-step explanation:
15+12=27
v-7=27
+7. +7
______
v=34
(4 + 2x)(6 + 2x) =
4(6 + 2x) + 2x(6 + 2x) =
24 + 8x + 12x + 4x^2 =
4x^2 + 20x + 24 <==
There would be a hole when x = -4.
If you factor both the top and the bottom, you will see that the factor (x + 4) is in both the numerator and denominator. Therefore, the would be a hole when x = -4 because that would also make the denominator 0.
Step-by-step explanation:
5x=4x+12(corresponding angle)
5x-4x=12
x=12
