-) 42x2 - 69x + 20 = 7x2-8

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)

set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.
