Part B: Solve the expression and explain why the answer is negative or positive.
2 answers:
Part A: 12•1/2= Elevation of city D Part B: The expression would equal 6, 12•1/2=6ft. This is positive because, the number used,12 ft, can be split into and still be positive. If the number was 1, the number would be negative.

= -36
(side 1)^2 + (side 2)^2 = hyp^2 [m^2-n^2]^2 + [2mn]^ = hyp^2 Then m^4 - 2m^2n^2 + n^4 + 4m^2n^2 = hyp^2 m^4 + 2m^2n^2 + n^4 = hyp^2 Then hyp = +sqrt(m^4 + 2m^2n^2 + n^4) = +(m^2 + n^2) (answer)
