21. college enrollment information about students' choices of majors at a small
college is shown in the table. in how many years will there be 2 times as many
students majoring in engineering than in business? in how many years will there be 2 times as many students majoring in engineering than in biology? write an equations with variables on both sides for part a and b. major: engineering 120 (started out)- 22 more each year business 105 (started out)- 4 fewer each year
biology 98(started out)- 6 more each year

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
