Answer:
t=5W+30 or C
Step-by-step explanation:
The pool already has 30 in it so you would initially be adding it, not multiplying it to anything. Then since every second 5 gallons of water is being added to the pool, you add the 30 gallons the pool already contains to 5W.
Answer:
7(b^2 -2)(b^2 +2)
Step-by-step explanation:
Factoring the common factor 7 from both terms, you get the difference of squares. That can also be factored.
v = 7(b^4 -4) = 7(b^2 -2)(b^2 +2)
The difference b^2-2 will have irrational factors, so does not meet the problem requirements. This is the factorization over integers.
