Read the following word problem, then choose which linear equation models the problem. A rectangular trampoline has an area of 338 square feet. The length of the trampoline is twice its
width. Find the dimensions of the trampoline.

A. 2w • w = 338
B. 2(w + w) = 338
C. 2w = 338
D. 2w + 2w = 338

A

Step-by-step explanation:

We know that length · width = area, width = w, and length = 2 * width = 2w so the answer is 2w · w = 338.

x/3-10=8

x/3=18

x=48

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
