Oil is pumped into a tank at a rate modeled by
R(t)= 3 cos (pi*t) + 5 measured in gallons/min. If there are
30 gallons in the tank when the pump starts and no oil is
being removed, how many gallons are in the tank after 102 seconds
seconds?

What expression is equivalent to (2x-1)(x-3)?

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)
