A is 5×10^7 because you are trying to move the decimal to get the number at the beginning to be lower than 10 but not a decimal so you move the decimal 7 times to get 5. Because you moved it 7 times you do ×10^7. The exponent would be negative if you had a small number but for this question it would be positive because it's a big number.

6 = 2(1) + 2(w)

6 = 2 + 2w

Subtract 2 from both sides to isolate 2w.

4 = 2w

Divide 2 on both sides to isolate w.

2 = w

Therefore 12 tiles are needed to cover the floor.
