U= {1,2, 8,9}, b={2,4,6,8}, c ={3,4,5,6}. find b\c

2,3,5,8

Step-by-step explanation:

B/C . . . thus

(2,4,6,8)/(3,4,5,6)

4 and 6 cancel out

so you are left with (2,3,5,8)

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

i think it would be 42cm
