Answer: 5</h3>
===================================================
Explanation:
Everywhere you see an x, replace it with -5. Then use the order of operations PEMDAS to simplify
Keep in mind that for the x^2 term, you are squaring all of x = -5, which includes the negative as well. So that means
x^2 = (-5)^2 = (-5)*(-5) = 25
but sticking a negative out front makes
-x^2 = -(-5)^2 = -25

<span>Are the lines in the diagram perpendicular, parallel, skew, or none of these?
l and m: neither
l and m intersect, but are not perpendicular.
l and n: skew
l and n are not parallel, but they do not intersect because they are not on the same plane.
m and n: perpendicular.
m and n intersect at a right angle</span>
