Consider the roots of a cubic equation with integral coefficients: -1, and -2. The root -1 has a multiplicity of 2. Which choice is
the cubic equation?
x² + 4x² + 5x+8 = 0
x² + 4x² + 5x+2=0
2x3 + 8x2 + 12x + 2 = 0
2x3 + 8x2 + 12x + 8 = 0

explanation:

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.

might be the correct answer will be question number 2

a.for lorena 14 hours makes $126   for 16 hours she makes 144

for julie 6 hours makes $72 for 21 hours its $252

b. julie makes more money than lorena julie makes $12 an hour and lorena makes $9
