Answer:

7x^2 + 5x

Step-by-step explanation:

(9x^2 + 8x) - (2x^2 + 3x)

Combine like terms

9x^2 - 2x^2 = 7x^2

Combine like terms

8x - 3x = 5x

Add the two terms together

7x^2 + 5x

PLEASE HELP WILL GIVE MANY POINTS QUICK PLEASE

Yanka [14]

Answer:

$v = 33.95m/s$

Step-by-step explanation:

Given

$h = 58.8m$ --- height

$u = 0$ --- initial velocity

$g = 9.8m/s^2$ --- acceleration

Required

The velocity when he hit the water

The velocity is then calculated using:

$v^2 = u^2 + 2gh$

This gives:

$v^2 = 0^2 + 2*9.8 * 58.8$

$v^2 = 0 + 1152.48$

$v^2 = 1152.48$

Solve for v

$v = \sqrt{1152.48$

$v = 33.95m/s$
