This is just substitution. so 3(2(3)-4(1/2)+3(-2/3)= 3(6-2-2)= 3(2) = 6. Basically you plug in the values they gave you for the variables and then just solve one step at a time
Answer:
For part A I think that the sides are the same because if both of the x+4's just add the 4's to each other and then you may get X. For Part B I believe that if you're adding still then you may still get the same number on both sides.
Step-by-step explanation:
Part A: Add the 2 fours and you may get you're X.
Part B: Add the 3x+4 and you might get your X.
I hope I helped :) and sorry if it's wrong.
Hey there!
The equation for finding the sum of the interior angles for a polygon with n sides is the following:
"Hepta-" means seven; thus, a heptagon has 7 sides.
Since a heptagon has 7 sides, n=7.
Now, let's plug in that value into the equation.
Thus, the sum of all interior angles in a heptagon is 900 degrees.
Have an awesome day! :)
