129
Step-by-step explanation:
all u have to do is add those two numbers
Answer:
(x-1)(x+1)(x+5)
Step-by-step explanation:
x^3+5x^2 - x-5=
x^3-x+5x^2-5=
x(x^2-1) +5(x^2 - 1)=
(x^2- 1)(x+5)=(*)
(x-1)(x+1)(x+5)
(*) A^2 - B^2 =(A-B)(A +B)
Answer:
a 56.25 minutes
b 9.6 miles
Step-by-step explanation:
To find the rate, we take the miles and divide by the minutes
rate = 8 miles / 50 minutes
.16 miles per minute
A. how long to run 9 miles
We want to use the formula
d =rt where d is the distance, rate is the rate and t is the time
9 = .16 *t
Divide each side by .16
9/.16 = .16/16 *t
56.25 = t
It will take 56.25 minutes
B We have a time of 1 hour
We want to use the formula
d =rt where d is the distance, rate is the rate and t is the time
t = 1 hour, but our rate is in minutes
1 hour = 60 minutes so t = 60 minutes
d = .16 * 60
d =9.6 miles
