URGENT PLS

the answer to your question is b.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5
