3 0

Step-by-step explanation:

Hey there!

Given;

= 2 {x}^{2}  - 2x - 40

<u>Solve</u><u> </u><u>it by</u><u> </u><u>using</u><u> </u><u>mid-term</u><u> </u><u>factorization</u><u>. </u>

<u>= 2 {x}^{2}  - 2x - 40</u>

<u>= 2 {x}^{2}  - (10 - 8)x - 40</u>

<u>= 2 {x}^{2}  - 10x + 8x - 40</u>

<u>Take</u><u> </u><u>common</u><u> </u><u>and</u><u> </u><u>simplify</u><u> </u><u>them to get </u><u>answer</u><u>. </u>

<u>2x(x - 5) + 8(x - 5)</u>

<u>= (2x + 8)(x - 5)</u>

<u>= 2(x + 4)(x - 5)</u>

<u>Therefore the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>option </u><u>D</u><u>.</u>

<em><u>Hope</u></em><em><u> </u></em><em><u>it helps</u></em><em><u>.</u></em><em><u>.</u></em>

2. Use the figure to find angle measures. In the figure, m ll n and x ll y.
xeze [42]

Answer:

See below ~

Step-by-step explanation:

<u>A.</u>

  • m∠5 = m∠10 (alternate angles)
  • m∠10 = 69°

<u>B.</u>

  • ∠4 + ∠14 = 180° (∠14 is equal to ∠8 as they are corresponding, and ∠8 is supplementary to ∠4)
  • ∠14 = 180° - 114°
  • ∠14 = 66°

<u>C.</u>

  • ∠5 = ∠12 (as ∠10 = ∠12 by alternate interior angles, and ∠10 = ∠5 as alternate angles)
  • ∠12 = 86°
