A= (1, 3, 5, 7, 9)
b = (2, 4, 6, 8, 10]
c = {1, 5, 6, 7, 9)
au (bc)=
(1,5,7,9)
(1,3,5,6,7,9)
(1,5,6,7,9)

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
