Hello macelynn190!



To solve this question we need to substitute the given values of 'a' & 'b' in the equation & then simplify it.
Given,
Now, substitute this in the place of 'a' & 'b'..

Lastly, simplify it...

- The answer is <u>-</u><u>9</u><u>/</u><u>2</u><u> </u><u>or </u><u>-</u><u>4</u><u>.</u><u>5</u>

No it can’t because calculating the perimeter, you would have to add all sides of the rectangle. If you added 11 + 11 + 24 +24, the perimeter would be 70 not 60.
Every function associates input values with output values. The domain of a function is the set of all the inputs the function accepts.
You will basically always find your function graphed with the inputs on the horizontal axis and the outputs on the vertical axis. This means that every point on the graph has coordinates
, and the domain is the set of all the x values.
The points on your red line have all coordinates
, where d starts from 0 and ranges up to 12. So, the domain of the function is ![[0,12]](https://tex.z-dn.net/?f=%20%5B0%2C12%5D%20)
