Simplify the expression where possible. (x 3y 2) 4

Match each equation with the operation you can use to solve for the variable. 1 subtract 10 2 divide by 10 3add 18 4add 10 5 subtact 18 6multiply by 5. 7multiply by 10. a 5 = 10p b p + 10 = 18 c p + 18 = 5 d 5p = 10

If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (cxd)(x)

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
