If the length is X
X+X+X = 9X+6
3X=9X+6
-6X=6
X=-1
but because length can't be negative X=1
To solve this, we'd need an answer with a whole level, which means we'll multiply everything by 4. This would mean that 1/3 is also multiplied by 4, making 4/3. Which means a whole level is made in 4/3 hours or 1 1/3 hours.
Y=x².
This is te function of a parabola open upward
the domain is all values of x ={x/x∈z}
Answer:
2x² - 3x - 2
Explain:
Use the FOIL method: (a +b)(c +d) = ac + ad +bc +bd.
2x² + x - 4x - 2
Collect like terms.
2x² + (x - 4x) - 2
Simplify.
2x² - 3x - 2
