Rectangle's Perimeter is P=2(w+l)
where w and l are width and length respectively
34=2(w+l)
17=w+l
w=17-l
now A=wxl
A=(17-l)xl
A=17l-l^2
30=17l-l^2
l^2-17l-30=0
now solve for l
we know that

Step-by-step explanation:
Answer:
length of rectangle = 32.25 cm
Width of rectangle = 10.75 cm
Step-by-step explanation:
Let the length of rectangle be x.
And width of rectangle be y.
According to the problem,
x = 3y {Since the length of a rectangle is equal to triple the width}
Also,
Perimeter of rectangle = 86
or 2 (x + y) = 86
Plug x =3y in the above equation
We get, 2(3y + y) = 86
2 * 4y = 86
4y = 43
y = 43/4 = 10.75
So, length of rectangle = 3 * 10.75 = 32.25cm
Width of rectangle = 10.75cm
ANSWER
Yes,the graph passes the vertical line test.
EXPLANATION
The graph above shows a function because if we draw a vertical line across the graph anywhere, it will never intersect the graph more than once.
This is what we call the vertical line test.
Since the graph of the function passes the vertical line test, the graph shows a function.
See graph
Therefore the correct answer is option C.
