Pascha is factoring the polynomial, which has four items. 3x^3-15x^2+8x-40
3x^2(x-5)+8(x-5)
Which is the completely factored form of her polynomial
(3x^2-5)(x+8)
(3x^2-8)(x+5)
(3x^2+8)(x-5)
(3x^2+5)(x-8)

1+1=2

Step-by-step explanation:

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )
