A group of four students are attempting to solve the equation 3(x+12)=48 . The table shows the first step each student takes in solving the equation.

48

Step-by-step explanation:

well lets simlify it. 3(x+12)=48 can also be 3x+36=48

idk i was trying to answer something. i hope this helps. have a wonderfull day.

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

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
