The length of the triangle for the pool table is the twice the sum of 5 and a number. If the rack is
gayaneshka [121]

Answer:

30 + 6x inches

Step-by-step explanation:

Let the required number be x

If the length of the triangle for the pool table is the twice the sum of 5 and a number

L = 2(5+x)

L = 10+2x

Since the triangle is quadilateral, this means that all sides are equal

Perimeter = 3L

Perimeter = 3(10+2x)

Perimeter = 30+6x

Hence the perimeter, in inches, of the triangle is 30 + 6x inches

What is the simplest form of the expression 2x(x â’ 6) â’ 7x2 â’ (13x â’ 3)? A. 5x2 â’ 25x 3 B. -5x2 â’ 25x 3 C. -5x2 x 3 D. -5x
kobusy [5.1K]

The simplest form of the given expression can be written as -5x² + 25x - 3.

The given parameters:

2x(x + 6) - 7x²  + (13x - 3)

The given expression can be simplified as follows;

2x(x + 6) - 7x² +  (13x - 3)

= 2x² + 12x -  7x² + 13x - 3

<em>collect similar terms together</em>

= (2x² - 7x²)  + (12x + 13x) - 3

= -5x² + 25x - 3

Thus, the simplest form of the given expression can be written as -5x² + 25x - 3.
