First, you want to establish your equations.
L=7W-2
P=60
This is what we already know. To find the width, we have to plug in what we know into P=2(L+W), our equation to find perimeter.
<span>60=2(7W-2+W) </span>
<span>Now that we only have 1 variable, we can solve. </span>
First, distribute the 2.
60=14W-4+2W
Next, combine like terms.
60=16W-4
Then, add four to both sides.
64=16W
Lastly, divide both sides by 16
W=4
To find the length, we plug in our width.
7W-2
7(4)-2
28-2
<span>L=26</span>
Answer:
x minus thirteen = <u>x</u><u> </u><u>-</u><u> </u><u>1</u><u>3</u><u>.</u>
Answer:
Answer is 72
Step-by-step explanation:
6 times 8 is 48. 3 needs to be divided by 2 to made into 1.5. Then multiply 48 and 1.5 to make 72ft your answer
The answer to that is 62.78
