F(1) = (1)^2 + 1 = 2
g(4) = 3*4+1 = 13
2f(1) + 3g(4) = 2*2 + 3*13 = 43
A typical shower drain can remove 480 gallons of water in 3 hours.
For the first-rate;
1,440 gallons in 3 hours
We calculate the unit rate.
By Dividing the total volume by the total time,
1440 / 3 = 480 gallons/ hours
For the second rate:
960 gallons in 120 minutes
Converting minutes to hours:
120 minutes = 2 hours
We calculate the unit rate.
By dividing the total volume by the total time,
960 / 2 = 480 gallons / hour
For the third rate:
720 gallons in 1.5 hours
We calculate the unit rate.
By dividing the total volume by the total time,
720 / 1.5 = 480 gallons / hour
Now,
480 gallons/ hour = 480 / 60 gallons/ minute = 80 gallons per minute

Just divide 5/4 = 1.25. Thank you.
Answer:
3(x^2-x-3)
Step-by-step explanation:
9x^2-3x-9
3(3x^2-x-3)
Proof:
3(3x^2-x-3) by distributive method
9x^2-3x-9
Hope this helps ;) ❤❤❤
