Which expression is equivalent to (2x^2 + 3)(x + 4)? A 2x^3 + 12
B 2x^2 + 11x + 12
C 2x^3 + 6x^2 + 4x + 12
D 2x^3 + 8x^2 + 3x + 12​

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
