The service elevator in a building operates only on floors 1 through 4 and floors 16 through 20. Each floor has a height of 15 feet.
This inequality shows the elevations, x, in feet, at which the service elevator
does not stop:
4< x/15<16
Graph the solution set showing the elevations at which the service elevator doesn't stop.

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)

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
