12x45 is 540. Now people don't ever ask something like this ever again. Ask your teacher if you don't get it. If you still don't get it ask somebody who knows it well.If anybody you know doesn't know it then ask Answes.com. Thanks
X-45=12 ________ +45 +45 ________ x= 57
45 x 12 = 540
4 x 12 - 45 + 8 = 48 - 45 + 8 = 3 + 8 = 11

45 30/12 = x/18; 12x = 30 x 18; 12x = 540; x = 540 ÷ 12 = 45
15 x 3 = 45, 12 x 2 = 24, 45 + 24 = 69
(x-12)^2= 45 x^2 - 24x + 144 = 45 x^2 - 24x + 99 = 0 Using quadratic formula : (24 +/- (180)^0.5) / 2 In exact terms (using surds) = 12 +/- 3 x (5)^0.5 OR = 18.7 or 5.29
to solve this, simply multiply 0.375 by 12. you will get 4.5
4.5
3x-15 = -12
12 X 12 is one square foot your area is 45 square feet therefore you would need 45 tiles. you might want to get extra just in case one breaks or something else happens.
