P = perimeter = 2L + 2W = 86 cm. Also, L = W + 4. Subst. W + 4 for L,
P = 2(W + 4) + 2W = 86 cm. Then 2W + 8 + 2W = 86 cm, and 4W = 78 cm.
Finally solving for W, W = (78 cm)/4, or 19.5 cm.
If W = 19.5 cm, then L = W + 4 cm = 19.5 cm + 4 cm = 23.5 cm
The rectangle's dimensions are 19.5 cm by 23.5 cm.
Since both the input and the output assume only integer values, the function is classified as discrete.
<h3>What are continuous and discrete variables?</h3>
- Continuous variables: Can assume decimal values, hence they are represented by rational numbers.
- Discrete variables: Assume only countable values, such as 1, 2, 3, …, hence they are represented by whole numbers, or even integers if it can be negative.
In this problem, all values on the table assume only integer values, hence the function is classified as discrete.

explanation:
the equation of the sum of interior angles are (n-2)x180
polygon above has 21 sides so you sub n as 21 and plug the equation in the calculator
Its 75 miles per hour hope you understand
Answer:
-6m^4-m^3
Step-by-step explanation:
First you move the parenthesis then you group the like terms after you group the like terms you get 
which is adding the similar elements and after you add similar elements you get -6m^4-m^3. Srry if this makes no sense
