Answer:

A, C, D

Step-by-step explanation:

As important rules of thumb that you should remember:

- the product of 2 negatives ALWAYS makes a positive

- the product of 2 positives ALWAYS makes a positive

- the product of 1 positive and 1 negative ALWAYS makes a negative

Now, look at the answer choices:

- "The product of two negative integers is positive"    this is true

- "The product of two integers with different signs is positive"   this is essentially saying that the product of a positive integer with a negative integer is positive, which is false

- "If two numbers are the same sign, then the product is positive"    this is true, as can be seen by the first two bullet points at the beginning

- "The product of a positive and a negative is negative"    this is true

- "If the signs of two integers are different, then the product is positive"    this is false because of the third statement above

The answers are A, C, and D.

Answer:

The product of two negative integers is positive=True

If two numbers are the same sign, then the product is positive=False

The product of a positive and a negative is negative=True

If the signs of two integers are different, the the product is positive=False

Step-by-step explanation:

The reason A and C are true is because of the rules of integers.

Two numbers with the same sign = positive product

Two numbers with different signs = negative product

This is how I learned it at my school, anyway. Hope this answers your question.

Hello there!
Goryan [66]

(x^2+3)^2 + 7x^2+21=-10

We want to convert this equation in terms of m, where m = x^2+3

While solving this problem, I instantly noticed the x^2+3 in the first term of the equation. Replace that with m.

m^2 + 7x^2+21=-10

Simplifying the rest is not as obvious. Using the distributive property, we can change [7x^2+21] to [7(x^2+3)]

Do you see the "m" in here? Look again if you don't.

Now we can simplify the equation to m^2 + 7m=-10 and this cannot be simplified further.

I'm always happy to help someone who appreciates the help! :D
