Which solution below contains an error?
3/x+4/6²=3x/x²+4/x²=3x+4/x²
1/x+2+1/x+2=2/x+2=1/x+1
2/x+1+8/x-6=2x-12/(x+1)(x-6)+8x+8 /(x+1)(x-6)=10x-4/(x+1)(x-6)

Iwould say d but i am not 100% positive

Heya dear

df =

both have same length

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
