You simply multiply the expression on the outside (in this case, 3) by each of the expressions inside the parentheses, and add everything up. In this case, 3x + 3 times 4.
The sum of 3x plus 2 and -4 plus 3 is 3x+1 if the equation is (3x+2)+(-4+3). If they are two separate questions, 3x+2 remains as itself while -4+3=-1.
-3x+14 = -4 -3x = -4-14 -3x = -18 x = 6
4 + 8x
3x + 4 = 16 3x = 16 - 4 x = 12/3 x = 4

3(x plus 3) expanded --> 3x+9
6x + 8
(3x+4)(x-2) 3x2 -6x+4x-8 3x2-2x-8
It is: 3x+4
The answer is y = -3x -4.
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
38*4 + 3 + 7 - 3x = 162 - 3x
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
The sum of 3x plus 2 and -4 plus 3 is 3x+1 if the equation is (3x+2)+(-4+3). If they are two separate questions, 3x+2 remains as itself while -4+3=-1.
3x+56 = 2x+4 3x-2x = 4-56 x = -52
9x2 + 12x + 4 = 9x2 + 6x + 6x + 4 = 3x(3x + 2) + 2(3x + 2) = (3x + 2)(3x + 2) = (3x + 2)2
