Answer:
The degree would be 4
Step-by-step explanation:
When you add polynomials without multiplying bases, you cannot add or subtract the degree. So the highest degree would be 4 in this case.
162 m^2
you can make a triangle in the corner with legs length s/2 and the angles are 45 degrees. in a 45 45 90 triangle, the legs are h/sqrt(2) where h is the hypotenuse. this means that s/2=9/2 sqrt(2), s=9 sqrt(2)
and s^2=162
A and C
27/100
A = 2(lw+hl+hw)
A = 366
