Answer:
x = -7
Step-by-step explanation:
6/x + 8/x + 5 =3
5x + 14 /x =3
Step 1: Multiply both sides by x.
5x+14=3x
5x+14−3x=3x−3x(Subtract 3x from both sides)
2x+14=0
2x+14−14=0−14(Subtract 14 from both sides)
2x=−14
2x
2
=
−14
2
(Divide both sides by 2)
x=−7
Check answers. (Plug them in to make sure they work.)
x=−7(Works in original equation)
I do not believe so, because a square is in the rectangle family. If a rectangle was in the square family, it would have to have all sides the same length, wich wouldnt make it a rectangle anymore.
