A^2 + b^2 = c^2
a = x
b = 14
c = x+10
x^2 + 14^2 = (x + 10)^2
( x^2 + 196 = x^2 + 20x +100 ) - x^2
( 20x +100 = 196 ) -100
( 20x = 96 ) / 20
x = 4.8

(y + 1)^3 would just be dividing the two

If you want it completely simplified, then it’s the following:

(y + 1)(y + 1)(y + 1)

= y^2 + y + y + 1 (y + 1)

= y^2 + 2y + 1 (y + 1)

= y^3 + y^2 + 2y^2 + 2y + y + 1

= y^3 + 3y^2 + 3y + 1
