Amaya used these steps to solve the equation 8x+4=9+4(2x−1). Which choice describes the meaning of her result, 4=5? A. Amaya made a mistake because 4 is not equal to 5.
B. No values of x make the equation true.
C. All values of x make the equation true.
D. The solution is x=4 or 5.

She followed the right steps because the original equation does end up turning into 4 = 5, which is a false statement or a contradiction. There are no values of x we can plug in to make the equation true.

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
