(2 x 1016) + (7 x 1016) =

Hi there! hopefully this helps!

9144.

Steps:

(2 X 1,016) + (7 X 1,016) =

2,032 + 7,112 = 9,144.

9144

Explanation:

2 x 1016 = 2032

7 x 1016 = 7112

2031 + 7112 = 9144

It's just steps after another :D

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.
