A rectangle of perimeter 74 cm is 7cm longer than it is wide. what is the length of each side?

Mumz [18]

I assume that you mean: the length is 7cm more than the width, and the perimeter is 74 cm.

If so, we can write down the following system, where l and w represent, respectively, the length and the width:

$\begin{cases}l=w+7\\2(l+w)=74\end{cases} \iff \begin{cases}l=w+7\\l+w=37\end{cases} \iff \begin{cases}l=w+7\\(w+7)+w=37\end{cases}$

We can easily solve the second equation:

$(w+7)+w=37 \iff 2w+7=37 \iff 2w=30 \iff w=15$

And finally solve for the length:

$l=w+7=15+7=22$

Given the function defined in the table below, find the average rate of change, in simplest form, of the function over the inter

Inessa [10]

The average rate of change, in simplest form, of the function over the interval 2 ≤ x ≤ 10 is 9

<h3>How to find the average rate of change, in simplest form, of the function over the interval 2≤x≤10?</h3>

The interval is given as:

2 ≤ x ≤ 10

From the table of values, we have

f(2) = 34

f(10) = 106

The average rate of change, in simplest form, of the function over the interval 2≤x≤10 is calculated as;

Rate = (f(10) - f(2))/(10 - 2)

This gives

Rate =(106 - 34)/(10 - 2)

Evaluate

Rate = 9

Hence, the average rate of change, in simplest form, of the function over the interval 2 ≤ x ≤ 10 is 9
