Answer:

x = -3

Step-by-step explanation:

You have the following equation:

3(2x+4)=-6\\

you first you distribution property in order to eliminate the parenthesis:

3*2x+3*4=-6\\\\6x+12=-6

next, you subtract 12 in both sides of the equation:

6x+12-12=-6-12\\\\6x=-18

Finally, you divide the equation by 6 and simplify:

\frac{6x}{6}=-\frac{18}{6}\\\\x=-3

hence, the solution to the equation is x = -3

How do I solve for the measures of the the interior angles of a polygon
Leni [432]

Answer:

Step-by-step explanation:

To solve for the interior angles for a polygon,

subtract 2 from the number of sides then multiply with 180

i.e, (n-2)180

e.g, in the case of a triangle, (3-2)180 = 1*180 = 180

As for square, (4-2)180 = 2*180 = 360

Hope u understand.
