5x^2+60x=0
x(5x+60)=0
x=0
and
5x+60=0
5x=-60
x=-12
therefore, the first option is correct
The correct answer is A. Each of the y values are 4 times their respective x values
SA=4pir^2
d/2=r
d=7.4
7.4/2=3.7
SA=4pi3.7^2
SA=4pi13.69
SA=54.76pi
pi=3.14 for this question
SA=171.9464
closest one is B

B IS ANSWER
Answer:
$10
Step-by-step explanation:
cost of one month of game play = x
1(35) + 3x + 2(35) + 5x = 185

-105 -105
8x = 80
/8. /8
x =10
