The answer to the question is b
Answer:
91.3 in³
Step-by-step explanation:
The volume of a pyramid can be found using the formula ...
V = (1/3)Bh
where B represents the area of the base, and h represents the height.
Since the base is square, its area will be the square of the side length, so the volume is ...
V = (1/3)·(7.4 in)²·(5 in) ≈ 91.3 in³
Find a number between 2.15 and 2.17 so one of the answers could be 2.16
Answer:
D
Step-by-step explanation:
Given
- 1(x + 7)(x - 4)
each term in the second factor is multiplied by each term in the first factor, that is
leaving the multiplier of - 1 for the time being
x(x- 4) + 7(x - 4) ← distribute both parenthesis
= x² - 4x + 7x - 28 ← collect like terms
= x² + 3x - 28
Hence
- 1(x² + 3x - 28) = - x² - 3x + 28 → D
