You have to distribute the minus sign to the second parenthesis, changing the sign of every term:

$-3y^2-8-(5y^2+1) = -3y^2-8-5y^2-1 = -8y^2-9$

The length of the rope needed is 15 feet

Given the following parameters;

Height of the pole = 9 foot

The distance from the <u>rope away from the base </u>of the pole is 12 feet

Required

Length of the rope.

To get the length of the rope, you will use the pythagoras theorem expressed as:

c² = a² + b²

Substituting the given parameters:

c² = 9² + 12²

c² =81 + 144

c² = 225

c = √225

c = 15 feet

Therefore the length of the rope needed is 15 feet
