She spent 21 minutes completing the math problems. But then you add the 9 minutes she spent checking. Your answer is 30 minutes in total
Speed=6 miles per hour
Distance =9.6 miles
Speed =distance /time
Time=distance/speed=9.6/6=1.6 hours
(-5x ⁵+14)-(11x ²+1+11x ⁵)
Like terms: -5x ⁵-11x ⁵ = -16x ⁵
Like terms also: 14-1 = 13
Simplified all together: -16x ⁵ - 11x ²+ 13
(Always put highest degree first)
A number 4 times as much as 25 is 100
Step-by-step explanation:
