If AB = 3, AD= 5, andDE= 6, what is the length of BC?

D. 3.6

Step-by-step explanation:

=> Taking proportionality of the similar sides to find BC

Multiplying 6 to both sides

BC = 3.6

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
