If you mean: 7x+21 = 105 Then the solution is: x = 12
It depends. Assuming that you mean 12 by 12 in. blocks, then you would need 105 of them, because 12 inches is one foot, and 1x1=1. 105 divided by 1 is 105.
I assume you mean 12" x 12". That's a square foot, so 105 tiles cover 105 square feet.
What you mean to ask is, how do you write 5.403 x 105 in standard form. That works out to be 540,300.
105+105=210.
