My math is super rusty but I came up with this answer
x+3/x+5
12
I think its 12 because that's the biggest number you can divide both 48 and 72 by and not have any left over or not have enough to divide again. I recommend to check and make sure though.
Answer:
Step-by-step explanation:
(x+3)(x-3)
x squared and -9 are both square numbers.
the square root of x^2 is x
the square root of -9 is 3. so you just need to write (x+3)(x-3)
you can check by expanding the brackets and the middle x terms should cancel out
10.5+(10.5*.4)=10.5+(4.2)=14.7lbs after the first month
