The length of a rectangle is half the width. Find the length of the rectangle if the perimeter is 42 cm.

All you have to do is divide 42 by 2 42 ÷ 2=21 would be your answer if you divided it correctly that would be your answer!

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
