Answer:
- 2x² + 2x + 11
Step-by-step explanation:
Given
x² + 6 - (3x² - 2x - 5) ← distribute parenthesis by - 1
= x² + 6 - 3x² + 2x + 5 ← collect like terms
= - 2x² + 2x + 11
Answer:
Brian's average speed: 14.73 mile/hour
The traveled distance by skiing he estimated: 11.0475 miles.
As the information provided in table, the time he spent for skiing is 0.75
=> The distance Brian traveled by skiing: 14.73 x 0.75 = 11.0475 (miles)
=> Brian's product is correct.
=> Rounding to the nearest whole number => 11.0475 = 11 (miles)
Rounding the Brian's average speed to the nearest whole number:
=> 14.73 = 15 mile/hour
Round the activity time to the nearest whole number:
=> T = 3 + 1.45 + 1.2 + 0.75 = 6.4 = 6 (hour)
Hope this helps!
