Answer:

Step-by-step explanation:

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.

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
