First distribute the 2(2+4x)
3x-4+4+8x
then just combine like terms.
8+11x
therefore
3x-4+2(2+4x)=8+11x<span />
Four $5 bills and two $1 bills
In total it’s six bills
5(4)=20 and 1(2)=2
20+2=22
The answer would be the third one .
Perpendicular would always be the opposite of your original slope.
Hope this helps! (:
4y+x= -1
-x -x
—————
4y=-x-1

4 4
=======
Y= -1/4x - 1/4
Hoped this helps
