Solve the system of equations and choose the correct ordered pair.
2y = 8x - 14
4y = 8x + 4

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

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.
