Add 8 to the input and then multiplies by 5

y = 5(x + 8)

Step-by-step explanation:

The first step is to add 8 to the input, you get x + 8. Then you need to multiply that number by 5. An equation that represents that is y = 5(x + 8).

*You can't just write down y = 5x + 8 because you are multiplying the result of x + 8 by five, not multiplying x by 5, then adding 8.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
