To solve this, we use the formula for the volume of the frustum of a cone which is expressed as:
<span>V= (H/6)[WL + (W+a)(L+b) + ab]
</span>V = 3/6 [(6 ft. × 8 ft.) + (6 + 14)(18 + 8) + (<span>14 ft. × 18 ft.)]
</span>V = 409.98 ft^3 <-----OPTION C
Answer:
The answer to your question is below
Step-by-step explanation:
(2x⁴ + 7x³ - 3x + 9) - (6x⁴ - 3x³ - 6x² - 17)
Step 1. take out the parenthesis, in the second term, change the signs
2x⁴ + 7x³ - 3x + 9 - 6x⁴ + 3x³ + 6x² + 17
Step 2. Group like terms
(2x⁴ - 6x⁴) + (7x³ + 3x³) + (6x²) + (-3x) + (9 + 17)
Step 3. Simplify like terms
-2x⁴ + 10x³ + 6x² - 3x + 26
