The differece of twice
a number and five is
three. find the number

Step-by-step explanation:

LEt the number be x.

2x - 5 = 3

2x = 3 + 5 = 8

x = 8/2 = 4

To solve the equation: add 5 to both sides and then multiply by 1/2.

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.
