Use the Distributive Property to expand 8(2x - 5y) - 7.

8(2x) - 8(5y) - 7

Step-by-step explanation:

To check if you've distributed properly:

8(2x) - 8(5y) = 16x - 40y,

8(2x - 5y) = 16x - 40y

8(2x) - 8(5y) = 8(2x - 5y)

answer: no, but if it does it's a obvious pattern.

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.
