Here is the answer OwO:
A 12-foot flagpole casts a nine-foot shadow. The measure from the top of the shadow to the top of the flag pole is 15.
Here is the explanation/work OwO:
<u><em>Switch sides.</em></u>
c^2=12^2+9^2
<u><em>12^2=144</em></u>
c^2=144+9^2
<u><em>9^2=81</em></u>
c^2=144+81
<u><em>Add the numbers: 144 + 81 = 225</em></u>
c^2=225
<u><em>For x^2 = f(a) the solution is √f(a)</em></u>
c = 15
Therefore, your answer will be 15.

Sorry if I am late. Hope this helps!! ^^
Nathaniel is correct. fractions are rational numbers
I think that it’s 3 , not to sure
L=n-2, W=4+L=n+2
A=LW, since L=n-2 and W=n+2 we have:
A=(n-2)(n+2) so it could be this expression or the expansion
A=n^2-4
