x^{2} +10x+2=0

x^{2} +2*5*x+2=0

x^{2} +2*5*x+ 5^{2} -5^{2}+2=0

x^{2} +2*5*x+ 5^{2}+2= 5^{2}

(x+5)^{2}+2=25

(x+5)^{2}=23

Andre ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes.
Vladimir79 [104]

Answer:

They do not run at the same rate because Jada ran at a rate of .150km per min, while Andre ran at .133333 km per minute.

Step-by-step explanation:

Andre ran : 2km/15min = .133333km per min

Jada ran: 3km/20min=.150km per minute

.150>.1333, so Jada ran at a higher rate of kilometers per minute.

Organic milk costs $2.52 per gallon. at this rate, how can the price of 4 gallons be determined?
asambeis [7]

Let's make an equation where x is the number of gallons and y will be the overall price.

2.5x=y; since it is $2.52 PER gallon, you need to multiply the amount of gallons by the cost. In this case, it is 4.

2.5(4)=10

So, the price of 4 gallons is $10.
