Answer:
a = - 4, b = 5
Step-by-step explanation:
Expand the left side, then compare the coefficients of like terms.
- 3(2x² + ax + b)
= - 6x² - 3ax - 3b, compare to - 6x² + 12x - 15
Compare coefficients of x- terms
- 3a = 12 ( divide both sides by - 3 )
a = - 4
Compare constant terms
- 3b = - 15 ( divide both sides by - 3 )
b = 5

Answer:
A.aas
Step-by-step explanation:
The answer to your question is x = -3
Given:
Triangular prism.
Base area : 37.4 square yards
height : 5 yards
To find the volume of the ramp based on the given figures, we simply multiply the base area by the height.
Volume = base area * height
V = 37.4 square yards * 5 yards
V = 187 cubic yards.
The volume of the triangular prism-shaped ramp is 187 cubic yards.
