20 % ( not sure how to explain this ) because 5 out of 20 is equal to 20 % cause 20 +20 + 20 +20+20 equal 100 so taking 5 people off would equal to 20%

Which of the following are solutions to the following equation?
Alecsey [184]

Answer:

x=-7

x=7

Step-by-step explanation:

we have

2x^{2}-98=0

Solve for x

Adds 98 both sides

2x^{2}-98+98=0+98

2x^{2}=98

Divide by 2 both sides

2x^{2}/2=98/2

x^{2}=49

take square root both sides

x=\pm7

therefore

The solutions are

x=-7

x=7
