If 280=n, then 350=
a) n/4
b)4n/5
c)4n/3
d)5n/4

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

no he doesnt because "-16' is negatiive

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.
