Im pretty sure it’s A because a squares area is base x height which would be 13x13= 169 then add the area of the triangle which would be 53.3, so 169+53.3 = 222.3

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

$6x - 7$
