A triangle has side lengths of (8.9w-3.8x)(8.9w−3.8x) centimeters, (8.5w+6.8y)(8.5w+6.8y) centimeters, and (8.4y+2.4x)(8.4y+2.4x) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

answer: x=1

step-by-step explanation:

f(x) = g(x)

x - 2 = -1

x = 1

therefore the graph should be a line showing x=1 which is vertical and passes on 1

hope it !
