What is the value of x in units

x = 25

Step-by-step explanation:

ΔBDR ~ ΔQDC

so

(24 + 40)/(15 + x) = 40/x

or

(24 + 40)/40 = (15 + x)/x

24/40 + 40/40 = 15/x + x/x

3/5 + 1 = 15/x + 1

3/5 = 15/x

Cross multiply,

3x = 15*5 = 75

x = 75/3 = 25

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
