1 x 140, 2 x 70, 4 x 35, 5 x 28, 7 x 20, 10 x 14.
280
100 & 140. The two numbers are: the mean ± half the range. Half the range is 40/2 = 20. So the two numbers are: 120 - 20 = 100 120 + 20 = 140
The two numbers that multiply to -140 and add up to -8 are 7 and -20. When you multiply them, 7 × -20 equals -140, and when you add them, 7 + (-20) equals -8.
14 times 10
The two numbers that add up to -140 and multiply to 4900 are -70 and -70. Since they are the same number, -70 + -70 equals -140, and -70 * -70 equals 4900.
5 and 9
There are infinitely many pairs of numbers. Some examples: 1 * 8400 1000 * 8.4 2400 * 3.5 sqrt(1500) * sqrt(47040)
