The equation that can be used to determine the dimensions of the base of the doghouse is x² + 4x = 21
<h3>
What is the equation?</h3>
A quadratic equation is an equation that usually has a single variable and it is raised to the power of 2.

Answer:
36cm^2
Step-by-step explanation:
Break it apart into rectangles/squares where you can figure out what the length of at least two sides are for each.
Then multiply and get the area of the smaller area.
Then add the areas up.
You're basically just breaking it down into smaller shapes, then adding the different parts back together.
Answer:
It is not a function.
Step-by-step explanation:
If the x input or the y output in the given equation have no meaning or does not have any sense, then it will not form a function. We need to see if there are two of the x - intercept which are same. Then the graph will be a straight vertical line. Also the slope of the function cannot be determined.
