4. 4-d<4+d
Do you want an answer? Or do you need help solving it?
4-d<4+d weather you see constants (like 4) or uknowns (like d) to be on opposite side of the inequality and still have the same sign (in this case +) you can remove them from the inequality -d<+d
So im guessing that the question was asking of wether or not the inequality holds
which it does , since, -d is smaller than +d , hence -d<+d
-d<+d isnt a answer choice :/
@neonumbrella5115 can you please help??
@SolomonZelman
So the first step would be to get the variables together right? So add d to both sides.
okay
whats the next step?
Is the number 4.4 or just 4? When you subtract 4 or 4.4 from both sides, you'll get an answer
just 4
is the answe d>-4?
@AlexandervonHumboldt2
When you add d to both sides, you get 4<2d+4 Then when you subtract four from each side, you get 0<2d Once you do the last step, then you're perfect!
so the answer is d>0?
