A 2.44x +5.52

B 2.44x +11.88

C 12.36x +5.52

D. 12.36x +11.88

= 12.36 x +  5.52

Step-by-step explanation:

(7.4x + 8.7) - (-4.96x + 3.18)

combine like terms

7.4x + 4.96x  + 8.7 - 3.18

= 12.36 x +  5.52

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
