16 Answer #2 It is 16 if you just count the 1 x 1 squares but the 16 squares also form a 4x4 square. There are also 2x2 squares and 3x3 squares in the pattern. 16 1x1 squares 9 2x2 squares 4 3x3 squares 1 4x4 square 30 squares (possibly more?)
2 x 2 = 4 squares
There is a formula for "the difference of squares." (x + 7)(x - 7) = 0 x = 7, -7
4
4 squares in a 2 by 2 grid 9 squares in a 3 by 3 grid 16 squares in a 4 by 4 grid 25 squares in a 5 by 5 grid 36 squares in a 6 by 6 grid 49 squares in a 7by 7 grid 64 squares in a 8 by 8 grid 81 squares in a 9 by 9 grid 100 squares in a 10 by 10 grid
(x - 16)(x + 4) = 0 so x = -4 or 16
You're suppose to use a limited set of 9 numbers so that the sum, difference, product or quotient is the same horizantally, diagonally and vertically.
There is a formula for the "difference of squares." In this case, the answer is (x - 17)( x + 17)
There are 4 squares in a 2 x 2 grid.
It is the difference of squares. (x-4) and (x+4) <--- answer

There are 9 4" squares in a sq/ft 9 X 5 = 45 4" squares
x=4From superscot85: How you solve it is to subtract 4 from each side leaving x = 4
2 x 2 = 4 squares
4 x 4 = 16For any grid n by n, the number of squares is equal to n2 (or n x n)
There is a formula for "the difference of squares." (x + 7)(x - 7) = 0 x = 7, -7
Take the product of the dimensions to solve this: 6 x 6 = 36 So your answer is 36 squares.
