I think you should write the equation to find perimeter such as P = 2(L + W). So the expression is 2[2(x+y) + 3(x - y)]
Simplified as 2[(2x + 2y + 3x - 3y)]
2(5x - 1y) combined like terms
10x - 2y is the expression for the perimeter of the rectangle

Answer:

2 1/10 and 21/10

Step-by-step explanation:

2.1 is 2 + 0.1 when expanded.

2 is just 2 and then 0.1 as a fraction is 1/10. The mixed number would be 2 1/10.

The improper fraction is just 21/10 (convert the mixed number into improper form).

Converting from mixed number to improper: Multiply the number in the front (in this case 2) by the denominator.

That is 2 x 10 which is 20. Then add that number (20) to the numerator. 20 + 1 is equal to 21.

21 would be our numerator and the denominator would stay the same (10).

21/10 is the improper form.

Give the equation of the horizontal asymptote shown below.

Oxana [17]

Polynomial division yields

$\dfrac{7x^2}{x^2+5}=7-\dfrac{35}{x^2+5}$

As $x\to\pm\infty$ , you have the remainder term approaching $0$ , so the horizontal asymptote is the line $y=7$ .
