HELP ME ASAP

(5x + 6)^2 + (4x)^2 = H^2

Substitute 8 for x

(5*8 + 6) + (4*8)^2 = H^2

46^2  +  32^2  = H^2

H^2 = 2,116  +  1,024

H^2 = 3,140    Take the square root of both sides.

H = Sqrt(3,140)

H = +or-  56.0357 - Use the + only in this case. 

its kinda small,is that 5x+8?

ok thx

im pretty sure its 56

Omg yesssss thankkk uuuuuu
