Answer:

  c.  (-7x+4)(-7x-4)

Step-by-step explanation:

The factoring of the difference of squares is ...

  a² -b² = (a +b)(a -b)

__

In each of these answer choices, you have a first factor of ...

  (a +b) = (-7x +4)

so, you're looking for a second factor that is ...

  (a -b) = (-7x -4) . . . . . . . . matches choice C

  (-7x +4)(-7x -4) results in a difference of squares

__

<em>Check</em>

  (-7x +4)(-7x -4) = (-7x)(-7x) +(-7x)(-4) +(4)(-7x) +(4)(-4)

  = (-7x)² +28x -28x -4²

  = (-7x)² -4² . . . . . . . . the difference of squares

<span>1. Two angles are complementary. One angle measures 50°. What is the measure of the other angle?
</span>complementary, sum of the angles = 90 
<span>
so 90 -</span> 50 = 40
<span>
answer is
C.40°


2.Two angles are supplementary. One angle measurement is 30° more than the other. What is the measure of the smaller angle?


</span>supplementary, sum of the angles = 180

One angle measurement is 30° more than the other.

105 is 30 more than the other angel of 75

answer 
measure of the smaller angle is 75
