Its D . Subtraction property of equation
Let me show you why
p+5-8
Subtract 5 from both sides
p+5-5=-8-5
p=-13
So , yeah its D
I got u.
-4n + 9 = -4n + 9

Answer: 10</h3>
====================================================
Explanation:
The two smaller triangles are proportional, which lets us set up this equation
5/n = n/15
Cross multiplying leads to
5*15 = n*n
n^2 = 75
----------
Apply the pythagorean theorem on the smaller triangle on top, or on the right.
a^2+b^2 = c^2
5^2+n^2 = m^2
25+75 = m^2
100 = m^2
m^2 = 100
m = sqrt(100)
m = 10
