Answer:
Real Zeros x = ±4
Complex zeros : x = ±3 i
Step-by-step explanation:
<u><em>Explanation</em></u>
f(x) = x⁴ + 5x² – 36
f(x) = x⁴ + 5x² – 36
= (x²)² + 9 x² - 4 x² - 36
= x² (x² + 9) - 4( x² +9)
= (x² -4 ) (x² +9)
f(x) = x⁴ + 5x² – 36 = (x² -4 ) (x² +9)
(x² -4 ) (x² +9) = 0
⇒ x² -4 = 0 and x² +9 =0
⇒ x² -2² = 0 and x² = -9
⇒ x = ±4 and x = ±3 i
Real Zeros x = ±4
Complex zeros : x = ±3 i
1 kg is equal to a little over twice the lbs. So if you have 75 kg it'll be over 150 lbs. Therefore 75 kg weighs more.

Answer:
∠7 = 51°
∠8 = 129°
Step-by-step explanation:
All of the obtuse angles are congruent, as are all of the acute angles. The acute and obtuse angles are supplementary.
∠8 = ∠1 = 129°
∠7 = 180° -129° = 51°

<em>Additional comment</em>
Technically, angles 1 and 8 are called "alternate exterior angles." As such, they are congruent. Angles 7 and 8 form a "linear pair." As such, they are supplementary.
