Answer:

(x-3)(x-5)

Step-by-step explanation:

X^2-8x+15

Break the expression into groups

(x^2-3x)+(-5x+15)

Factor out x from x^2-3x

Factor out -5 from -5x+15: -5(x-3)

=x(x-3)-5(x-3)

Factor out common term x-3

=(x-3)(x-5)

Thanks for letting me help!!

the Honda CRV gets 37 miles per gallon on average how much carbon dioxide will be admitted if the Honda were driven 400 miles

Pani-rosa [81]

According to the equation located here: https://www.1728.org/glwarmng.htm burning one gallon of gasoline produces 19.3 pounds of carbon dioxide.

So, if a car gets 37 miles per gallon and if it travels 400 miles, it will use 10.81 gallons of gasoline and will produce 19.3 * 10.81 = 208.63 pounds of carbon dioxide.
