The equation is y = -x - 1
A+b+8 = 11-3c
a+b+3c = 11-8
a+b+3c = 3
a = b-1
c = b+1
b-1+b+3*(b+1) = 3
2b-b+3b+3 = 3
4b = 3-3
4b = 0
b = 0
a = b-1
a = 0-1
a = -1
c = b+1
c = 0+1
c = 1
a = -1, b = 0, c = 1
Answer:
The correct option is (b).
Step-by-step explanation:
The formula for the side of a cube of surface area SA is as follows :

When SA = 180 m²

When SA = 120 m²

Difference,

So, the correct option is (b).
The answer is false. this is because you have to get the x by itself so you divide both sides by 8.
8x = 0
x = 0
