1 yard =36 inches so ,36/15 =2.4 2.4 is the scale factor if the scale is 15 inches equals 1yard
15 and 2
x2-2x-15 = (x+3)(x-5) when factored
120. 120/8 equals 15 and 120/5 equals 24.
(x - 5)(x + 3)
I really don't know.
3 is a factor and dividing by 3 gives x + 15 = 8x
4/30 just factor out a 2 2/15 ------ so 2/15 = 2/15 ========
(x + 5)(x - 3)
(x-3)(x-5) = 0
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
