I can help! Do you have an example problem that I can show you step by step?
Not sure about remainder theorem but I'm sure that the last terms should all multiply tho the last term
see the expanded form is -45
so the last terms of each binomial should multiply to -45
3 times -5 times ?=-45
-15 times ?=-45
divide by -15
?=3
the question mark is 3
12*14*3= 504 square feet
504/42= 12
C. 12 rolls
100pi/10pi this is irrational but reduces to 10, a rational number
