Answer:
6.7
Step-by-step explanation:
6-1.5+(11/5)=6.7
Let
x---------> the length of the rectangle
y--------> the width of the rectangle
we know that
A=84 ft²
[area of rectangle]=x*y-----> 84=x*y-----> equation 1
x=y-5------> equation 2
substitute 2 in 1
84=[y-5]*y-----> 84=y²-5y---------> y²-5y-84=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
y=12
x=y-5-----> x=12-5-----> x=7
the answer isthe length of the rectangle is 7 ftthe width of the rectangle is 12 ft
Answer:

Step-by-step explanation:
To find the slope, use the equation to find slope. The picture below shows what it looks like.
Using the equation, substitute the values in the x and y values.
Then solve
If it says sum it is addition.When it says quotient it is division.When it says decrease it is subtraction.And when it says twice as Much it is multiplication
