The third option should be correct
First distribute: -4h - 20 + 4h
Combine like terms: -20
The answer is -20
A cube has 6 sides (like a dice)
if one side is 14 cm ^2
that means that we have to multiply it by 6
so 14 (cm 2) x 6 = 84cm 2
1.) 6x-8y=18, 2x+8y=6 → Multiplication property of equality
2.) 8x=24 → Addition property of equality
3.) x=3 → Division property of equality
4.) 3(3)-4y=9 → Substitution property of equality
5.) 9-4y=9 → Simplify
6.) -4y=0 → Subtraction property of equality
7.) y=0 → Division property of equality
