Given that the pictured triangles are similar, find the lengths sides DF. Round your answers to the nearest tenth.
AC
AB
F
EF
BC
B
AB = 12
AC = 16
BC = 16
EF = 7

check above link.

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.

assuming this is from a math graphing problem.

7 would be on the x-axis which is the horizontal line on the graph

84 would be on the y-axis which is the vertical line on the graph

i would say c

step-by-step explanation:

19479 is the answer ^^
