<em>The volume of the cube is </em> $\mathit{\frac{27}{z^3x^{9}}}$ <em>cu in.</em>

Step-by-step explanation:

<u>The Volume of a Cube</u>

Let's have a cube of side length a. The volume of the cube is:

$V=a^3$

The cube of the image has a side length of

$\displaystyle a=\frac{3x^{-3}}{z}\ inches$

Simplifying the expression of the base by converting the negative exponent in the numerator to the denominator:

$\displaystyle a=\frac{3}{zx^{3}}\ inches$

Now find the volume:

$\displaystyle V=\left(\frac{3}{zx^{3}}\ inches\right)^3$

Applying the exponents:

$\displaystyle V=\frac{3^3}{z^3x^{9}}\ inches^3$

$\displaystyle V=\frac{27}{z^3x^{9}}\ inches^3$

The volume of the cube is $\mathbf{\frac{27}{z^3x^{9}}}$ cu in.

Solve by completing the square

Sveta_85 [38]

$\qquad\qquad\huge\underline{{\sf Answer}}☂$

Let's solve ~

$\qquad \sf \dashrightarrow \: {x}^{2} + 8x = 33$

$\qquad \sf \dashrightarrow \: {x}^{2} + 8x +16 = 33 + 16$

$\qquad \sf \dashrightarrow \: (x + 4) {}^{2} = 49$

$\qquad \sf \dashrightarrow \: x + 4 = \sqrt{49}$

$\qquad \sf \dashrightarrow \: x + 4 = \pm7$

Hence, there are two solutions ~

1. when x + 4 = 7

$\qquad \sf \dashrightarrow \: x + 4 = 7$

$\qquad \sf \dashrightarrow \: x = 7 - 4$

$\qquad \sf \dashrightarrow \: x = 3$

2. when x + 4 = -7

$\qquad \sf \dashrightarrow \: x + 4 = - 7$

$\qquad \sf \dashrightarrow \: x = - 7 - 4$

$\qquad \sf \dashrightarrow \: x = - 11$

I hope you understood ~
