They are: 4*5*7 = 140
How about: 4*5*7 = 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.
70*2
You can multiply any numbers together.
140
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.
