The correct answer is the one on the top right corner.
4-x=3
Double the 3 witch is =6
And add 8 witch is
6+8=14
This is how I would do it:
-8x=28-4y divide the entire equation by 4
-2x=7-y Put y back on the left and put x on the right
y=7-2x.
B+c+(c-b)+(b-c). That is your expression. b 11 c 16
First, let's convert the variables to real numbers: 11+16+(16-11)+(11-16)
Now, let's solve that equation. 11+16+5+(-5)
5+(-5) cancels out, so all we have left is: 27
That is your perimeter.
you could tell if it is even or odd by how many number are odd and how many are even...majority wins...
13 odd
45 odd
24 even
17 odd
hope i can help,and have a nice day!! :)
