Since a cube is defined to have the same measurement in all three dimensions, it's volume can be calculated by raising the measurement of one side to the power of three.

In the problem we are given a measurement in centimeters and we are tasked to find the volume in m³. To make the calculation easier, we can just convert the measurement immediately since we know 100cm = 1m. Following this conversion, 13cm will be equal to 0.13m.

For the volume we'll get: 0.13^{3}=0.002197 cubic meters or 2.197*10^{3} cubic meters if you are more comfortable expressing it in scientific notation.

A) Factorise 2x² - 9x - 5 (x-5)(2x+1) (2) <br>b) Hence, simplify fully 2x^2- 9x - 5 3x – 15x (2) ​
Lyrx [107]

Answer:

Step-by-step explanation:

<u><em>b).</em></u>

2x² - 9x - 5 = ( x - 5 )( 2x + 1 )

3x² - 15x = 3x ( x - 5 )

\frac{(x-5)(2x+1)}{3x(x-5)} = \frac{2x+1}{3x}

Which of the following correctly uses exponents to write "6 factors of 2"? A.62 B.26 C.6 ∙ 2 D.12
kotegsom [21]

Step-by-step explanation:

1. 6 factors of 2 means, 2 multiplied by itself 6 times.  It can be written in the form of exponents as 2⁶.

2. 2^m{\cdot} 2^n

The law of exponent is : x^a{\cdot} x^b=x^{a+b}

So,

2^m{\cdot} 2^n=2^{m+n}

The correct option is (A).

3. If the power of any number is 0, then the value of that number is equal to 1.

So,

23^0=1

Hence, this is the required solution.
