Evan is getting ready for his shift at the Grateful Dead concert T-shirt stand that sells only rainbow tie-dye shirts and dancing bears shirts. He has to make at least 15 shirts. Each rainbow tie-dye shirt takes 3 minutes to make and each dancing bears shirt takes 5 minutes to make, but he has only up to one hour to make these shirts. Write a system of inequalities for the situation. and how to graph​

Multiply. −2x(6 x 4 −7 x 2 +x−5) express the answer in standard form. enter your answer in the box.
