It would be
(X^4+2X^2) -119(X^2-2X) then you would simplify
X^4+2X^2-119X^2-2X
So it would be
X^4+117X^2-2X=0
So basically X is undefined
The solution is 25% acid, which means 2.5 liters acid (10 x .25).
<span>you need that 2.5 liters to be 10%, or 1/10th the total. </span>
<span>the total would have to be 25 liters (2.5 x 10) so when you add to 10 to get 25 you get </span><span>15 liters. Hope I helped!</span>
Answer:
x=−14
Step-by-step explanation:
Step 1: Subtract x from both sides.
3x+20−x=x−8−x
2x+20=−8
Step 2: Subtract 20 from both sides.
2x+20−20=−8−20
2x=−28
Step 3: Divide both sides by 2.
2x
2
=
−28
2
x=−14
