If 3 times x = 4 then x = 4/3 or 1.3333 (3 recurring)
X=4/3
18 x 4 x 3 = 216
2 x 3 x 4 = 24
4 x 3 x 6 = 72
7 x 3 x 4 = 84
6 x 3 x 4 = 72
The answer is 25. In the sum 3 x 3 + 4 x 4... you perform the multiplication first.
4 x 16 x 3 = 192
4 x 3 x 3
We are multiplying here, so we can combine all of the constants and make that the coefficient for the x. 4 * x * 3 = (4 * 3) * x = 12x.
No, it equals 420.
