Answer:
16x³ + 9x² + 9x + 13
Step-by-step explanation:
Given
6x³ + 8x² - 2x + 4 and 10x³ + x² + 11x + 9
Sum the 2 expressions by adding like terms, that is
= (6x³ + 10x³) + (8x² + x²) + (- 2x + 11x) + (4 + 9)
= 16x³ + 9x² + 9x + 13
The answer to the question is h=64 degrees
Answer:
4 feet/minute
explanation:
The rate of descent = (10 feet)/(2.5 mn) = 4 ft/min
You need to add 1 3/4, 2 1/3, and 2 3/4.
But before you do that you need to make them decimals.
Add 1.75, 2.33, and 2.75
Equals 6.83
Then subtract it by 20.00
Equals 13.17
Then you make that a decimal
13 17/100
