Hey there! I'm happy to help!
We know that the perimeter is 2L+2W. Le'ts plug in the values 3 and 5 from our ratio and see what our perimeter would be with that.
2(3)+2(5)
6+10
16
How can we get this 16 to 64?
64/16=4
So, we need to multiply this length and width by four to get 64 as our perimeter!
3*4=12
5*4=20
We can plug this into our perimeter equation
2(12)+2(20)
24+40
64
Therefore, our length is 12 and our width is 20.

Answer:
y = -3, slope = 0
Step-by-step explanation:
1) First, find the slope of the line. Substitute the x and y values of the given points into the slope formula,
, and solve:

Thus, the slope is 0.
2) If a line has a slope of 0, that means it is horizontal. All horizontal lines are represented by the equation y = a number. That number is determined by the y-value of all the points the line intersects. Thus, find the y-value of the given points and put it into the equation. Looking at the given points, that number would be -3, so y = -3 is the equation.
Let Frances time = F
9 minutes less than frances time = F - 9
F - 9 is your expression
