Bart has 15 coins in his pocket, all dimes and quarters. The total value of the coins is $2.85 How many quarters are in his pocket?

12*c

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
