Answer:
2x^3-8x^2+8x+12
Step-by-step explanation:
split them up
use distributive property
2x-6(x-2)
2x^2-4x-6x+12(x+1)
use distributive property again
2x^3+2x^2-4x^2-4x-6x^2-6x+12x+12
simplify
2x^3-8x^2+8x+12
I forgot if you can divide it by 2 or not to simplify it even more. If you can, divide it by 2. I forgot the rules
If you divide it by 2, then the answer is
x^3-4x^2+4x+6
Answer:
x > 4
Step-by-step explanation:
Given
2(x + 6) < 3x + 8 ← distribute left side
2x + 12 < 3x + 8 ( subtract 3x from both sides )
- x + 12 < 8 ( subtract 12 from both sides )
- x < - 4
Multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative quantity.
x > 4
Answer:

Step-by-step explanation:
Answer:
~8.7
Step-by-step explanation:
So we know that the formula for volume is 3.14 * r^2 * h.
So first we do 1738/23 to get an ugly ~ 75.6 Now he have to square root that to get r.
The square root of 75.6 is ~ 8.7
