MrMuchimi

Answer: \left \{ {{2x+3y=7.20} \atop {4x+2y=8.80}} \right.

Step-by-step explanation:

Let be "x"  the price per pound for grapefruit, "y" the price per pound for oranges.

We know that Steve buys 2 pounds of grapefruit and 3  of oranges for $7.20.

This means that the sum of the products of 2x and 3y is $7.20. Then, we can write this equation to represent it:

2x+3y=7.20

Kennedy buys 4 pounds of grapefruit and 2 pounds of oranges for $8.80.

This means that the sum of the products of 4x and 2y is $8.80. Then, we can write this equation to represent this:

4x+2y=8.80

Therefore, we get that the system of equations that models the situation is:

\left \{ {{2x+3y=7.20} \atop {4x+2y=8.80}} \right.

Answer:

\frac {x^{3}-4x^{2}-20x+32}{x^{3}+2x^{2}-4x-8}

Step-by-step explanation:

make the denominator same

\frac{(x^{2}-4)(x-2)}{(x^{2}-4)(x+2) }-\frac{(2x+20)(x+2)}{(x^{2}-4)(x+2)}

then expand

\frac {x^{3}-2x^{2}-4x+8}{x^{3}+2x^{2}-4x-8} - \frac {2x^{2}+24x+40}{x^{3}+2x^{2}-4x-8}

join

\frac {x^{3}-4x^{2}-20x+32}{x^{3}+2x^{2}-4x-8}

i think but not sure
