Lee has a jar of 100 pennies. she adds groups of 10 pennies to the jar . she adds 5 groups. what numbers does she say?

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
