Because 3 x 4 = 12
Just multiply across: 3x4=12 12x7=84 84x2=168
8x8 = 64 so it is 64 (the y) 3x4 = 12 so it is 12 (the x) 64+12 is 76.
The four solution values of x of 3x4 + 7x3 + 4x2 = 0 are: x = -11/3, -1, 0 (repeated) 3x4 + 7x3 + 4x2 = 0 ⇒ x2(3x2 + 7x + 4) = 0 ⇒ x2(3x + 4)(x + 1) = 0 ⇒ x2 = 0 → x = 0 (repeated) or (3x + 4) = 0 → x = -4/3 = -11/3 or (x + 1) = 0 → x = -1
25 x 50 = 1,250
Because 3 x 4 = 12
No. 6 x 2 = 2 x 6 is.

50 x 50 x 100 equals 250,000
25 x 50 = 1,250
50 x 0.10 = 5
