SOLUTION: Determine the value(s) of x such that the area of the parallelogram formed by the vectors a = (x + 1, 1, −2) and b = (x, 3, 0) is 41. There are little arrows above vectors a

Question 1163663: Determine the value(s) of x such that the area of the parallelogram formed
by the vectors a = (x + 1, 1, −2) and b = (x, 3, 0) is 41.
There are little arrows above vectors a and b. I just dont know how to type them in. Thank you.
