Can u help me and put a picture of the work u did

but which class are u may know that first

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140

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
