Use this formula a2 − b2 = (a + b)(a − b)

<span>(x+1)^2-(x-1)^2  in this case, a = x+1, b = x-1</span>

<span>= [(x+1) + (x-1)] *  [(x+1) – (x-1)]</span>

=(x +1 + x – 1) *(x +1 – x +1)

= 2x * 2

<span>=4x</span>

Given the graph of a line y=−x. Write an equation of a line (there are many) which intersects the line, but is not perpendicular
BaLLatris [955]
This would be any equation whose slope isn’t -1 or 1.

If the slope was -1, the lines would be parallel because the have the same slope.

If the slope was 1, the lines would be perpendicular because 1 is the negative reciprocal of -1.

Any line with any other slope will intersect with y=-x.

Hope this helps!

Angle e measures 126LaTeX: ^\circ∘. What is the measure of LaTeX: \angle∠h?
SVEN [57.7K]

Answer:

m\angle h=126^o      

Step-by-step explanation:

we know hat

<u><em>Vertical Angles</em></u> are the angles opposite each other when two lines cross. They are always congruent.

In this problem

m\angle h=m\angle e ----> by vertical angles

we have

m\angle e=126^o ---> given problem

therefore

m\angle h=126^o
