a is equivalent to 18.

2(42 - a) = 48
2(42) + 2(-a) = 48     *distributive property of multiplication
84 - 2a = 48
-2a = 48 - 84
-2a = -36
-2a/-2 = -36/-2
a = 18

to check:
2(42-a)   = 48
2(42-18) = 48
2(24)      = 48
48          = 48

What is the answer of a^2+b^2-(a-b)^2
Alex787 [66]
2b^2. This is because you have a positive a^2 and a negative so they cross it one another so it just leaves the b’s.

None of these lines are parallel or perpendicular. I assume you may have mistyped the original equation. If the original equation had a 4 next to the x instead, then the following is true. 

The first is parallel
The second is neither
The third is perpendicular.
