x2 + 4x – 21
Enter your answer in the box.

Step-by-step explanation:

x² + 4x -21 = x² + 7x - 3x -3*7

= x*(x + 7) -3(x + 7)

=(x + 7)*(x-3)

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
