Which statement shows how the product of (x + 7)2 demonstrates the closure property of multiplication?

Illusion [34]

The true statement that show the closure property of multiplication :

<h3>a. x² + 14x + 49 is a polynomial</h3>

$\texttt{ }$

<h3>Further explanation</h3>

<em>If equation ax³ + bx² + cx + d = 0 has roots x₁ , x₂ , and x₃ then</em>

$x_1 + x_2 + x_3 = - \frac{b}{a}$

$x_1 x_2 + x_1 x_3 + x_2 x_3 = \frac{c}{a}$

$x_1 x_2 x_3 = - \frac{d}{a}$

Let us now tackle the problem!

$\texttt{ }$

This problem is about Polynomial.

$(x + 7)^2 = (x + 7)(x + 7)$

$(x + 7)^2 = x^2 + 7x + 7x + 7(7)$

$(x + 7)^2 = x^2 + 14x + 49$

$x^2 + 14x + 49$ is a polynomial.

$x + 7$ is polynomial.

It demonstrates the closure property of multiplication.

Answer:

(A) 49

Explanation:

Most of the equation is just explaining what length and width is.

Area = L (length) · W (Width)

Option One:

Length: 9

Width: 5

9 · 5 = 45

There is no option for 45 so we need to check option two.

Option Two:

Length: 7

Width: 7

7 · 7 = 49

There is an option for 49, so that is our answer.

Basically, they are just explaining that Area = L · W, and to check both options to see if there is an answer.
