D is what i got. because that is the only possible answer.
Answer:
7 x² y z⁴ = 7 ⋅ x² ⋅ y ⋅ z³ ⋅ z
21 x² y⁵ z³ = 7 ⋅ 3 ⋅ x² ⋅ y ⋅ y⁴ ⋅ z³

Answer:
75 degrees and 105 degrees
Step-by-step explanation:
Supplementary angles are those angles that sum up to 180 degrees
So angle A + B = 180 or B = 180 - A
then A/B = 5/7
7A = 5B
7A = 5(180 - A)
7A = 900 - 5A
12A = 900
A = 75
then B = 180 - A = 180 - 75 = 105
