Answer:

Area of Walkway = 12x+16

Step-by-step explanation:

Area of Garden = 4(2.5x + 1.5)  <u>[Garden Area]:  (10x + 6)</u>

Area of Garden and Walkway = 5.5(4x+4) <u>[Total Area]:  (22x + 22)</u>

Area of Walkway = [Total Area] - <u>[</u>Garden Area<u>] </u>

Area of Walkway = [5.5(4x+4)] - <u>[</u>4(2.5x + 1.5)<u>]</u>

Area of Walkway = [22x+22)]   - <u>[</u>10x + 6)<u>]</u>

<u>Area of Walkway = 12x+16</u>

How do you simplify that?

Answer:

-2/radical 3

radical 8 can be written as 2 times radical 2

radical 6 can be written as radical 2 *radical 3

you have radical 2 as common for both so you can cancel those

and you remain with -2 on the top and radical 3 on the bottom

so the answer is -2/radical 3
