<br />a) A and B are the subsets of a universal set U in which there are n (U) = 54,<br />n (A) = 32, n (B) = 22 and n (<br />AB) = 9.<br />(i) Draw a Venn-diagram to illustrate the above information.<br />(ii) finda intersection b complement

Step-by-step explanation:

hope this will help u.Plz give the answer as brainest

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

if x decreases by 4 then y increases by 10
