(SAT Prep) In the figure, what is the length of BC? A.25 B.15 C.18 D.22 (Please include an explanation)

Iam stuck on one problem. my mind is in absoloute vacation mode. i literallty just need to finish this to be done will give brainliest and all my points if i have to! 1- point free throw and 2- point feild goal. he made 35 shots, and scored 62 points how many of each shot did he make in 1 minute? (i already did the math. he made 8 1-point free throws and 27 2-point feild goals.) 1. write two equations for the problem. (i had a major brain fart.)

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'

Solve the equation: x - 9 = -6 + 5 a. 21 b. 7 c. 14 d. 2
