Divide. Show your work.<br><br> (6x^4-5x^3+6x^2)/2x^2
serg [7]
We can do like we did before, distribute the denominator,

\bf \cfrac{6x^4-5x^3+6x^2}{2x^2}\implies \cfrac{6x^4}{2x^2}-\cfrac{5x^3}{2x^2}+\cfrac{6x^2}{2x^2}\implies \cfrac{6}{2}\cdot \cfrac{x^4}{x^2}-\cfrac{5}{2}\cdot \cfrac{x^3}{x^2}+\cfrac{6}{2}\cdot \cfrac{x^2}{x^2}&#10;\\\\\\&#10;3 x^4x^{-2}-\cfrac{5}{2}x^3x^{-2}+3x^2x^{-2}\implies 3x^{4-2}-\cfrac{5}{2}x^{3-2}+3x^{2-2}&#10;\\\\\\&#10;3x^2-\cfrac{5}{2}x+3x^0\implies 3x^2-\cfrac{5}{2}x+3

y(x)=f(x)

whose solution is f(x).

Megan's dog Sparky eats 4 1/4 cups of food each day explain how Megan can determine how much food to give Sparky if she needs to
olga_2 [115]
To determine the new amount you need to find out what 2/3 of 4 1/2 is equal to. What you see "of" in an algebraic expression or equation, replace it with (×).

2/3 of 4 1/2 =
2/3 × 4 1/2 =

Convert 4 1/2 to an improper fraction.

2/3 × 9/2 =

Now multiply and reduce

18/6 = 3

The new amount of dog food is 3 cups.
