a square has a perimeter of 52 mm. The square is dilated by a scale factor of 3. what is the side length of the resulting image?

39

Step-by-step explanation:

Since a square has 4 equal sides, it's safe to do to get each side length (each side is 13 mm).

Dilating a side means you're multiplying it by the scale factor. This means that you're doing to each side (each side is 39 mm).

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)
