Which expression is equivalent to 1/3(12x+6x-21)

marin [14]

Answer:

$6x-7$

Step-by-step explanation:

$\frac{1}{3} (12x + 6x -21)$

break it into pieces

$\frac{1}{3}*12x = 4x$

$\frac{1}{3}*6x=2x$

$\frac{1}{3} *-21=-7$

put it all together

*since there's no negative in front of the other numbers except 7 they're positive so you add them*

$4x + 2x - 7$

simplify

$6x - 7$

Answer:

$\large\boxed{(4x^2 + 8x - 2) - (2x^2 - 4x + 3)=2x^2+12x-5}$

Step-by-step explanation:

$(4x^2 + 8x - 2) - (2x^2 - 4x + 3)\\\\=4x^2 + 8x - 2 -2x^2 -(- 4x)- 3\\\\=4x^2+8x-2-2x^2+4x-3\qquad\text{combine like terms}\\\\=(4x^2-2x^2)+(8x+4x)+(-2-3)\\\\=2x^2+12x-5$

Lines on a railroad track are parallel lines.
