Which expression is equivalent to 3 sqrt[2y^3] x 7 sqrt[18y], if y>0? (see picture for easier understanding)

A — 21y sqrt[20y]
B — 21y^2 sqrt[6y]
C — 63y sqrt[2y]
D — 126y^2

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
