c) 15 + 3 - 4 = 14

d) 10 x 2 + 1 = 21

a. 4,7

b.30,35

c.15,14

c.10,21

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.
