F(2) = 3(2)^2 + 2(2) + 4
= 3(4) + 4 + 4
= 12 + 8
f(2) = 20
f(a+h) = 3(a+h)^2 + 2(a+h) + 4
= 3(a^2 + 2ah + h^2) + 2a + 2h + 4
f(a+h) = 3a^2 + 6ah + 3h^2 + 2a + 2h + 4
Answer:
The revenue would be $ 440
Step-by-step explanation:
Consider the correct complete question is,
"Roundup Rackets restrings a tennis racket for $22. If the store restrings 20 rackets each month, what is the monthly revenue from restringing rackets."
Thus,
The price for restrings each tennis racket = $ 22,
Number of rackets re stringed in a month = 20,
Hence, the monthly revenue = price of restrings each tennis racket × number of rackets re stringed
= 22 × 20
= $ 440
5/22 I’m pretty that’s the answer
Answer:
B) 5 hours
Step-by-step explanation:
First, find the amount of mph between 60 and 80:
80 - 60
= 20 mph
Since the speed increases 4 mph per hour, we can find how long it will take to get to 80 mph by dividing 20 by 4:
20/4
= 5
So, the correct answer is B, 5 hours
