The factors of 480 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, and 480. The factor pairs of 480 are 1 x 480, 2 x 240, 3 x 160, 4 x 120, 5 x 96, 6 x 80, 8 x 60, 10 x 48, 12 x 40, 15 x 32, 16 x 30, and 20 x 24.
Let label one of the numbers with x, and the other one with y. So, xy = -240 x + y = 8 y = 8 - x substitute this into the first equation; x(8 - x) = -240 8x - x^2 = - 240 -x^2 + 8x + 240 = 0 or multiplying by -1 both sides; x^2 - 8x - 240 = 0 (x + 12)(x - 20) = 0 x + 12 = 0 or x - 20 = 0 x = -12 or x = 20 So these numbers are -12 and 20. Check: -12 + 20 = 8 (-12)(20) = -240
The product of 8 and 30 is 240.
I'm no expert but I'm guessing this may help you... odd x odd = odd even x even = even odd x even = even for negatives and positive multiplying... n x n = p p x p = p n x p = n i hope this helps you! another thing that works is halving and doubling for example: 16x15=240 8x30=240 4x60=240 2x120=240 1x240=240
15% of 240 is 36 Let x be the quantity we are looking for So to find this using a proportion, look at 15/100=x/240 so 100x=15x240 and x=36
