Step-by-step explanation:
4. 120° ~ vertical angles are congruent
5. 13° ~ vertical angles are congruent
6. 70° ~ supplementary angles
7. 115° ~ supplementary angles
Step-by-step explanation:
x³ - 4x² + 3x
= x(x² - 4x + 3)
= x(x -3)(x - 1)
× = 0, 1, 3
Answer:
a) 4106.25 gallons
b) $46
Step-by-step explanation:
