"What's my numbers Add 5 to me then divide by 7. If you add 12 then subtract 7 you get 10 wat number am I

The correct answer is 30

Step-by-step explanation:

Add 5 to 30 and you get 35 divide that by 7 and get 5 add 12 to 5 and get 17 then subtract 7 and get 10.

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.
