Answer:
Step-by-step explanation:
Plug in 6 for k, since k=6.
6+12=18
18 is your final answer.
Answer:
The equation is x-18 + 8x = 180 (because they form a linear pair of angles.
Each angle measure:-
x-18 + 8x = 180
x + 8x = 180 + 18 (-18 becomes +18)
9x = 198
x = 198/9
x = 22
Angle 1 = x-18 = 22-18 = 4 degrees
Angle 2 = 8x = 8 * 22 = 176 degrees

Answer:
k = 12
Step-by-step explanation:
(x^2 + 16x + 64) - (x^2 + 4x - 32)
distributing - 1
x^2 +16r + 64 - x^2 - 4x + 32
12x +96
take a factor of 12
12(x + 8)
K = 12
