Determine which expression is equivalent to 3/4 - x (1/2 - 5/8) + (-3/8x). a. 1/8 - 7/8x b. 1/2x c. -3/4x d. 3/4 - 1/4x

.95

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.
