Answer:
90,000
Step-by-step explanation:
<span> Perimeter <em>p</em> means adding up the four sides of a rectangle.
Step 2. Let <em>w</em> equal the width.
Step 3. Let <em>w+3</em> equal the length.
Step 4. Then you'll have this really confusing equation: P=w+w+w+3+w+3=4w+6=30
And it will give you <em>w= 6</em>

I graphed this line below.
Start with an open dot on 7.
The reason we use an open dot is because x
does not equal 7, it is only greater than 7.
So from your open dot, draw an arrow to the right
to represent all numbers greater than 7.
Finally, state your answer in set notation if possible.
It is read as {x: x > 7}.
