(i picked c am i right? ) what is the product in lowest terms?

-8/9*5/6

a.
– 1

b.
-13/15

c.
-20/27

d.
-1/5

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

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.
