$1500 X 0.05 = $75. Add $1500 and $75 = $1, 575
(X-5)(X+4)=0 so X-5=0 -----X=5 and X=4=0 so X=-4 it factors to (X-5)(X+4) so X=5,-4
5+x=x+5 is an example of the commutative property of addition.
(x + 7)2 = 5 x + 7 = ±√5 x + 7 - 7 = -7 ± √5 x = -7 ± √5
x^(3) + 125 => x^(3) + 5^(3) This factors to (x + 5)(x^(2) - 5x + 5^(2) ) or (x + 5)(x^(2) - 5x + 25) NB The clue is to spot that the constant (125) is a cubic numbers ( 5^(3)). Similarly with other 'cubic factorings'.
2/5 of 1500 is 600.
1500 x 5% = 75
2 x 2 x 2 x 2 x 3 x 5 = 240 2 x 2 x 3 x 5 x 5 x 5 = 1500
1500 / 2500 = x% 1500 / 2500 * 100/1 = X 15/25 * 100/1 = X 3/5 * 100 /1 = X 300 / 5 = X 60 = X so 1500 / 2500 = 60%
1500
5 percent of 1500 is 75.5% = 5/100 and 5/100 x 1500 = 755% is 75.
