Answer:

Step-by-step explanation:
Let
x ------> the number of dogs Larry walked
y -----> the number of dogs Kyle walked
we know that
The linear equation that represent this scenario is equal to

Since both of the angles are supplementary, you'd set the expressions up into an equation equal to 180(degrees).
So, your equation should look like:
22x + 4 + 35x + 5 = 180.
Next, you combine your like terms so that your next move will look like:
57x + 9 = 180.
Then you'd follow the subtraction and division property, so your next moves will look as the following:
57x + 9 - 9 = 180 - 9 equals 171
57x / 57 = 171 / 57 equals 3
So, finally, your answer is: x = 3.
Answer:

Step-by-step explanation:
Width=(Length-2) units
W=(L-2) units
Area of the rectangle= 35 square units
Area = length* Width

Subtracting 35 both sides:

Solving the quadratic equation for 'L' ;
Using factorization:

Taking common from the equation :

OR

The length cannot be negative, therefore Length(L)= 7
