Find the volume of a CUBE if its side length is : x+2 in polynomial form

goldfiish [28.3K]

Volume = Length x Length x Length

Volume :

(x + 2) (x + 2) (x + 2)

= (x² + 4x + 4)(x + 2)

= x³ + 2x² + 4x² + 8x + 4x + 8

= x³ + 6x² + 12x + 8

Answer: x³ + 6x² + 12x + 8

Answer:

$x=1$

Step-by-step explanation:

Because vertical angles are always equal, we want to solve $50x+10=70x-10$ .

We can add 10 to both sides to get $50x+20=70x$ .

We can subtract $50x$ from both sides to get $20=20x$ .

Lastly, we divide both sides by 20 to get $1=x$ .

So, $\boxed{x=1}$ and we're done!

The check is left as an exercise to the reader.
