I NEED HELP!! (100 POINTS) Kian wants to solve the equation 2x = -2x + 4. How could he use graphs to solve this equation?

Drag statements into order to complete an explanation.

Uhh give me a sec it is a lot aight mane

Step-by-step explanation:

- graph the line that models -2x+4

- identify all points of intersection of the two graphs

- solutions to the equation are the x-coordinates of points of intersection

ur welcome :)

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
