Answer:

Can only be simplified through calculator using decimal equivalents.
Step-by-step explanation:
The perimeter of a rectangle is the formula P=2l+2w. Here
and
. So the perimeter is:

25/45=(5∗5)/(5∗9)=5/9
5/9 is the answer.
Answer:
For a rectangle with length 3x+4 and perimeter of 10x+18, what is the width of the rectangle
Answer:
<h3>n>-5/2</h3>
Step-by-step explanation:
First, you have to isolate it on one side of the equation. Remember that, isolate n on one side of the equation.
6n-3>-18
6n-3+3>-18+3 (Add 3 from both sides.)
-18+3 (Solve.)
-18+3=-15
6n>-15
6n/6>-15/6 (Divide by 6 from both sides.)
-15/6 (Solve.)
-15/6=-5/2
n>-5/2
In conclusion, the correct answer is n>-5/2.
