Answer:
Part 1)
Part 2)
Part 3)
Part 4)
Part 5)
see the attached figure
Step-by-step explanation:
Solve each quadratic equation
Part 1) we have

Adds 32 both sides

Divide by 2 both sides

take square root both sides

therefore
The solutions are (-4,4)
Part 2) we have

Adds 100 both sides

Divide by 4 both sides

take square root both sides

therefore
The solutions are (-5,5)
Part 3) we have

Adds 55 both sides


take square root both sides

therefore
The solutions are (-8,8)
Part 4) we have

Adds 140 both sides

take square root both sides

therefore
The solutions are (-11,11)
Part 5) we have

Adds 18 both sides

Divide by 2 both sides

take square root both sides

therefore
The solutions are (-3,3)
0.75 (1/2x) = 60
60/3 is 20, which is 25% of her remaining money,
So her total remaining money is $80.
Then 80 x 2 = 160
