A^2 + b^2 = c^2
40^2 + x^2 = 48^2
1,600 + x^2 = 2,304
-1,600 -1,600
x^2 = 704
(square both)
x = 26.53....
So the mattress is about 26.5 inches off the ground.
Hope this helps!
Equation is (x+2)^2 - x^2 = 7676
solve the equation by first opening the bracket of (x+2)^2 by A^2 + 2AB +C^2
you'll end up with 4x + 4 = 7672
thus x = 1918 and the next number is 1920.
