<h3>
2 Answers: B and D</h3>
===================================================
Explanation:
Choice B is one answer because -2 and 2 are additive inverses that add to -2+2 = 0
Choice D is a similar story. We have -5+5 = 0
In general, if x is some number then -x is its additive inverse. So we can say x+(-x) = 0 or -x+x = 0. In short, additive inverses add to 0.
Parallel slope = 2
This is because the original line has slope 2. Parallel lines have equal slopes.
--------------------------
Perpendicular slope = -1/2
The original slope 2 or 2/1 turns into -1/2 after flipping the fraction and the sign. Note the original slope and perpendicular slope multiply to -1. This is true for any pair of perpendicular lines where neither line is vertical.

Step-by-step explanation:
5 ft needs to be in inches, so multiply by 12 (inches per foot) ten you can compare.
I used a math calculator to evaluate this expression you just plug it in and it gives you the answer with all the steps. use the app FX math junior, but this is the answer ; 2419/720=3.3597
