what would have a product of -40?
well, what numbers multiply to 40?
example: 8*5 = 40
so,
-8*5 = -40
8 * -5 = -40
Now, pick any other factors of 40. As long as an odd number of them are negative, the result is -40
2(-2)(-2)(-5) = -40
-10 * 4 = -40
and so on.
Not as hard as it looked, was it?
Here are the answers!
1. -120
2. -56
3. 8 * -5
4. -75
5. 600
100% correct! Hope this helps :)
Just to ask am i going to have to wait along time?
That depends on when a math teacher comes online.
ok you are online can you help me? It would realy make my day.

To find two numbers that have a product of -40, we need to consider the properties of multiplication.
First, we know that two positive numbers always have a positive product, so we cannot select two positive numbers.
Next, we know that two negative numbers multiplied together will result in a positive product. Therefore, we cannot choose two negative numbers either.
So, to find two numbers that have a product of -40, we need to have one positive number and one negative number. By multiplying a positive number with a negative number, we can achieve a negative product.
Now, we can find the solution by trying different combinations. Let's start by considering the factors of 40: 1, 2, 4, 5, 8, 10, 20, 40.
We need to assign opposite signs to two factors such that their product is -40. Let's try different pairs:
1. 1 * -40 = -40 (not a product of -40)
2. 2 * -20 = -40 (not a product of -40)
3. 4 * -10 = -40 (not a product of -40)
4. 5 * -8 = -40 (bingo!)
So, the two numbers that have a product of -40 are 5 and -8.
