It takes one and a half minutes to swim a length. How many length can I swim in 12 minutes

Answers

I think the answer is 8 because it is like a ratio.
1.5 : 1
12 : ?
so 12/1.5= 8 so to get to 12 you multiply 1.5 by 8 and you would do the same thing to the other part of the ratio, and 1*8 is 8. Hope this helped.

Which polynomial has (3x + 2) as a binomial factor? 6x3 + 3x2 + 4x + 2 12x2 + 15x + 8x + 10 18x3 – 12x2 + 9x – 6 21x4 + 7x3 + 6x + 2

Answers

If binomial (3x+2) is a factor of some polynomial, then number $x=-(2)/(3)$ is this polynomial's root. Check all polynomials:

A. For the polynomial $6x^3 + 3x^2 + 4x + 2,$

$6\left(-(2)/(3)\right)^3 + 3\left(-(2)/(3)\right)^2 + 4\left(-(2)/(3)\right) + 2=-(16)/(9)+(4)/(3)-(8)/(3)+2=-(10)/(9)\neq 0.$

B. For the polynomial $12x^2 + 15x + 8x + 10,$

$12\left(-(2)/(3)\right)^2 + 23\left(-(2)/(3)\right) + 10=(16)/(3)-(46)/(3)+10=0.$

C. For the polynomial $18x^3-12x^2 + 9x-6,$

$18\left(-(2)/(3)\right)^3 -12\left(-(2)/(3)\right)^2 + 9\left(-(2)/(3)\right) -6=-(16)/(3)-(16)/(3)-6-6\neq 0.$

D. For the polynomial $21x^4 + 7x^3 + 6x + 2,$

$21\left(-(2)/(3)\right)^4 +7\left(-(2)/(3)\right)^3 +6\left(-(2)/(3)\right) +2=(112)/(27)-(56)/(27)-4+2\neq 0.$

Answer: correct choice is B

Answer:

B 12x2 + 15x + 8x + 10
