Formula: Area = length * width
Substitute in what you know: 42 = length * 6
Divide both sides by 6 to get the length: length = 7
Formula: Perimeter = 2 (length + width)
Substitute in what you know: P= 2 (7+6)
Solve: Perimeter = 26 ft
I believe the answer is
7x^3-2x^2-5
30 percent is 30/100 as a fraction so as a decimal it would be 0.30
-1.25, multiply both by 5, -45 divided by 36 is -1.25
3/8 of 24 = 9
Therefore the answer is 9 students.
