Answer:
Since A={a,b}, then 
. Remember that the Cartesian Product of two sets A, B is defined by
. Then
X = 5 so that would mean if you plug it into both equations, segment CD would be 32 units long.
Answer:
x⁴ + 6x² + 9
Explanation:
To answer this question, we will multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final expression.
This can be done as follows:
(x² + 3)(x² + 3)
x²(x²) + x²(3) + 3(x²) + 3(3)
x⁴ + 3x² + 3x² + 9
x⁴ + 6x² + 9
Hope this helps :)
