Step-by-step explanation:
I believe it is 3 because you are multiplying each number by 3 to get your bigger shape
If you use the distributive property, you will multiply 4 by 2x to get 8x and 4 by -4 to get -16.

If you want infinitely many solutions the equations on both sides of the equal sign need to be the same. So, k would need to be -16.
Answer:
X+81=180'
x=180-81
x=99
A=99(Being co interror angle)
B=81
Hence,
x=99
A=99
B=81
