To find factors that add up to 240 and also add up to 140, we need to solve a system of equations. Let's represent the two factors as x and y. We have the equations x + y = 140 and x + y = 240. By solving this system, we find that the factors are 100 and 140.

To find two numbers that add up to 240, you can set up an equation as x + y = 240. Since the numbers can be any combination, there are infinite solutions. For example, one possible solution could be 120 + 120 = 240. Another solution could be 100 + 140 = 240.

It adds up to 1260°, so 140° each angle
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.
16 if you count the repeated twos, 10 if you don't.
15 x -16 = -240 15 + -16 = -1
The two numbers that multiply to 140 and add up to 7 are 14 and -10. When you multiply them, 14 × -10 equals 140, and when you add them, 14 + (-10) equals 4. Thus, the correct pair is 14 and -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.
To find two numbers that add up to 240, you can set up an equation as x + y = 240. Since the numbers can be any combination, there are infinite solutions. For example, one possible solution could be 120 + 120 = 240. Another solution could be 100 + 140 = 240.
