If it is a 90 degree angle. Strait up and strait flat. Picture the corner of a perfect square. Hope this helps! :)
Step-by-step explanation:
82 + 16 = 98
Expression A: 122 - 82 = 40
Expression B: 2(62) + 23 = 147
Expression C: 102 - 32 = 70
None of them has the same value as 82 + 16.

Answer:
24 m
Step-by-step explanation:
The area formula tells us ...
22 = xy . . . . . square meters
Adding twice this to the quadratic constraint gives ...
(x^2 +y^2) +2(xy) = (100) +2(22)
(x +y)^2 = 144
x +y = √144 = 12
The perimeter is double this amount, so is ...
P = 2(x +y) = 2(12) = 24 . . . . meters
C=(b,0) therefore you'll have to add the coordinates AC and BD
The work is equivalent to the dot product of the two vectors.
