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.

<em>The true statement that show how the product of (x + 7)² demonstrates the closure property of multiplication:</em>

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

Round your answer to the nearest tenth of a cubic centimeter.

Zigmanuir [339]

Answer:

22.1

Step-by-step explanation:

Because of it being a pyramid we must use the equation Bh1/2

B = L + W we assume that the base is a perfect square meaning all sides are the same length B = 4.8 + 4.8 = 9.6 then we multiply by the height

9.6 x 4.6 = 44.16 next you divide by 2 or multiply by .5

44.16/2 = 22.08 then finally rounding to the nearest tenth

making 22.1 cubic inches
