-48

Step-by-step explanation:

A couple things to note:

In math, product means multiply. So the question wants you to multiply -12 and 4.When you multiply two numbers, and one of them is negative, the entire problem is negative. If two of them are negative, the answer is positive. Basically, an odd number of negatives means the answer is negative, and an even number of negatives means the problem is positive.

Using both of those things, we can now just multiply 12 and 4 like normal, and then add the negative to get -48 :)

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable
