What is the y-intercept of the equation 3y + 2x = 12? A. (0,4)
B. (4,0)
C. (4,4)
D. (0,0)

if you want to check that you can just plug in 3(4) + 2(0) =12

but yeah it is a.

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.
