5x2 + 25x + 30 This expression describes a parabola, and can be factored out as follows: = 5(x2 + 5x + 6) = 5(x + 2)(x + 3)
This is a quadratic equation in the form of: 52 - 25x + 30 = 0 Solve by using the quadratic equation formula: x = 2 or x = 3 Or by factorising: (5x-10)(x-3) = 0, which means that x = 10/5 or x = 3
Using algebra to solve this problem (12 + .25x = 30), the answer (x) is 72.
25X + 30 = 15X subtract 15X from each side 25X - 15X + 30 = 15X - 15X 10X + 30 = 0 subtract 30 from each side 10X + 30 - 30 = 0 - 30 10X = -30 divide both sides integers by 10 (10/10)X = - 30/10 X = - 3 ----------------check in original equation 25(- 3) + 30 = 15(- 3) - 75 + 30 = - 45 - 45 = - 45 ----------------checks
30 + 30 + 30 + 30 + 30 + 30 = 180

10 + 10 + 10
it equals 30 cents because 5 plus 25 equals 30
If it isn't a trick question it is 736. 700 plus 30 equals 730 and then plus 6 equals 736.
