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
The product of 3 and 15 is 45.
