1. you are given a problem that involves multiplying a positive number and a negative number. which of the following are reasonable answers? select all that apply. [] -2 [] 2 [] -5 [] 5 2. which of the following are reasonable answers for the product of two negative numbers and a positive number? select all that apply. [] 20 [] 10 [] -20 [] -10

The multiplication of numbers with opposite signs is negative, while the multiplication of numbers with the same sign is positive:

So, the multiplication of a positive number and a negative number must be negative, and the only feasible answers are -2 and -5.

Similarly, if you multiply two negative numbers and a positive number, the two negative numbers will give a positive number as a result, and then when you multiply it by a positive number, you still have a positive number:

1) -2, -5

2) 20, 10

Step-by-step explanation:

We are given the following information in the question:

The product of two integers can be done in the following manner:

Product of a positive number and a positive number is positive.

Product of a positive number and a negative number is negative .

Product of a negative  number and a positive number is negative .

Product of a negative  number and a negative  number is positive.

1) Multiplication of a positive number with a negative number

-2, -5

Because the product will be negative.

2) Multiplication of two negative numbers and positive number

20, 10

Because the product of two negative will be a positive and product of two positive number is positive.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
