A cube is a square shape, so both sides ( length and width) of a face would be the same.

Find the length of the side by finding the square root of the area of the face:

Length = √400 = 20 cm.

Volume is Length x Width X height.

Volume = 20 x 20 x 20 = 8,000 cm^3

Answer:

D. $\frac{22x + 48}{x^2 - 36}$

Step-by-step explanation:

Given:

$\frac{15}{x - 6} + \frac{7}{x + 6}$

Required:

Find its equivalent expression

Solution:

Add both fractions

Thus,

$\frac{15}{x - 6} + \frac{7}{x + 6}$

$\frac{15(x + 6) + 7(x - 6)}{x^2 - 36}$

$\frac{15x + 90 + 7x - 42}{x^2 - 36}$

$\frac{15x + 7x + 90 - 42}{x^2 - 36}$

$\frac{22x + 48}{x^2 - 36}$

Therefore,

$\frac{15}{x - 6} + \frac{7}{x + 6} = \frac{22x + 48}{x^2 - 36}$

Total sq units of dotted rectangle = 3*5=15sq units

Shaded area= 15-(3*4*1/2+2*5*1/2)

=15-(6+5)

= 15-11

= 4 sq units

The statement(s) that are true is that the measure of the reference angle is 45°.

<h3>What is the conversion of radians to degrees?</h3>

The conversion of an angle in radian to a degree can be determined by the multiplication of the given angle in radian by 180/π.

From the given information:

$\mathbf{\theta = \dfrac{7 \pi}{4}}$

To degrees, we have:

$\mathbf{\theta = \dfrac{7 \pi}{4} \times \dfrac{180}{\pi}}$

$\mathbf{\theta =315^0}$

A reference angle is an angle that measures the remaining distance (called the terminal distance) to the x-axis.

315° is in the 4th quadrant, i.e.

= 360° - 315°

= 45°

Therefore, the statement(s) that is true is:

The measure of the reference angle is 45°.
