1st number can be 0-9 = 10 numbers
2nd number can be 0-9 = 10 numbers
3rd number can be 0-9 = 10 numbers
10 * 10 * 10 = 1000 combinations
5.2 represented with significant figures. 5.2083 (3 repeating) is the actual answer.
I need to know which question it is though
The perimeter of the square is 28-12n.
We have a square. The length of the side of the square is (-3n + 7). We need to find the perimeter of the square. The perimeter of a shape is defined in geometry as the total length of its boundary. The perimeter of a shape is calculated by adding the lengths of all the sides and edges that surround it. The perimeter of a shape is the sum of all the sides of the shape. The square has four sides, and all the sides of the square are equal to each other. The perimeter of the square is four times the length of one of its sides.
P = 4*(-3n + 7) = -12n + 28
