The marginal revenue function has x measured in years and MR(x) in hundreds of dollars per year. Use numerical integration to find the total revenue over the given period
MR(x) = 0.09x3 -0.4x2 + 6x
(0 sxs 12)
The total revenue is $
(Simplify your answer.)

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
