Hello!
Your answer is: 7
(X = "<em>A number</em>")
<em>"11 more than four times a number is 39"</em> in equation form is: 4X + 11 = 39

4X = 28
then divide both sides by 4 to get:
X = 7
I hope this helps, and have a nice day!

 14.87
Step-by-step explanation:
use the Pythagorean theorem 
a^2+b^2=c^2
C being the longest side of the triangle 
14^2+5^2=C^2
