The area of a rectangle is the result of multiplying its length times its width. So the rectangles length and width are factor pairs of the area.
The number 36 has four non-equal, whole number factor pairs: (1,36) ; (2,18) ; (3,13) ; (4,9)
*note : (6,6) makes a square not rectangle
The number 15 has only two whole number factor pairs (1,15) and (3,5)
Y/4-7=3
y/4=7+3
y/4=10 /4
y=40
Slope = change in y / change in x
Slope = (4 - -8) / (-14 - -6)
Slope = 12/-8
Simplify:
Slope = -6/4
It will be 57 because if 9 are nickles in the rest are pennies
