Answer:
1. 4c-8
2. 8x-8
Step-by-step explanation:
multiply the number on the outside of the brackets by the numbers on th inside
4*c=4c
4*-2=-8
so 1. 4c-8
and for question 2:
8*x=8x
8*-1=-8
8x-8
The answer would be D. Because the solution is where the lines intersect.
They only intersect at the origin in D.
It is A due to the fact that the over all angle is 90 degrease.
2n - 7 = 5n -10
-5n -5n
-3n - 7= -10
+7 +7
-3n = -3
-3/-3 -3/-3
n= 1
