Answer:

Formula: a² + 2ab + b² = (a + b)²

The square root of 1/9x² = 1/3x so a = 1/3x and b = 1/5y.

The answer is (1/3x + 1/5y)².

Neporo4naja [7]

Answer:

The system of equations is

$x+y=15$

$19x+8y=164$

Step-by-step explanation:

Let

x------> the number of videos of new releases

y-----> the number of classics videos

we know that

$x+y=15$ ------> equation A

$19x+8y=164$ ------> equation B

Using a graphing tool

Solve the system of equations

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is $(4,11)$

see the attached figure

therefore

the number of videos of new releases is $4$

the number of classics videos is $11$
