\huge\text{Hey there!}


\huge\textbf{Equation:}

\mathsf{6n - 8(n + 4)}


\huge\textbf{Solve: }

\mathsf{6n - 8(n + 4)}


\huge\textbf{Distribute \boxed{\bf -8} within the parenthesis:}

\mathsf{= 6n - 8(n) - 8(4)}

\mathsf{= 6n - 8n - 32}


\huge\textbf{Combine the like terms: }

\mathsf{= (6n - 8n) - (32)}

\mathsf{= 6n - 8n - 32}

\mathsf{= -2n  - 32}


\huge\textbf{Therefore, your answer should be:}

\huge\boxed{\frak{{ -2n  - 32}}}\huge\checkmark


\huge\text{Good luck on your assignment \& enjoy your day!}

The diagonal of a square is 14 m, what is the perimeter
Olin [163]
The diagonal of a square is obtained by using Pythagorean theorem. Letting x be the side of the square, 
                                       x² + x² = 14²
Solving x from the equation gives x a value of approximately 9.899 m. The perimeter of a square is four times the length of its side. Thus, the perimeter of the square is approximately 39.60 meters.

An object is moving at a speed of 4 meters per month. Express this speed in inches
BartSMP [9]

Answer:

<h2><em>0.22inches/hour</em></h2>

Step-by-step explanation:

Given the speed of an object to be 4metres/month, we are to express the speed in inches/hour.

First we will need to convert 4meters to inches

From the conversion factors given,

1 foot (ft) = 0.305 meters (m)

x ft = 4metres

cross multiply

x * 0.305 = 4*1

x = 4/0.305

x = 13.115ft

4 metres = 13.115ft

Then we will convert 13.115ft to inches

From the conversion factors,

1 foot (ft) = 12 inches (in)

13.115ft = y

cross multiply

y = 13.115*12

y = 157.377 inches

Hence<em> 4 metres = 157.77inches.</em>

For 1 month to hour

First we need to convert month to days and from the conversion factor

1 month = 30 days

Next is to convert 30days to hours

Since 1 day = 24hours

30days = z

z = 30* 24

z = 720hours

Hence <em>1 month = 720hours</em>

On converting 4metres/month to inches/hour

4metres/month = 157.77inches/720hours

4metres/month = 0.219inches/hour

<em></em>

<em>Hence the speed of the object in inches per hour to the nearest hundredth is 0.22inches/hour</em>

<em></em>
