step by step
A=1/2h(B+b)
15=1/2h(4+1)
15/(4+1)=1/2h
15/5=1/2h
3=1/2h
h=2*3
h=6
Answer:
(i) U' = Φ
(ii) A∩A' = Φ
(iii) A – ( B U C) = {5,7,9}
(iv) A' U ( B U C ) = {2,4,6,8,10}
(v) A' U ( B' ∩ C') = {2,4,5,6,7,8,9,10}
Step-by-step explanation:
9/a
8/a - 6/a + 7/a
Since the denominators are the same, we can add the numerators
8-6+7 =9
Then put it over the common denominator a
6 is the correct answer
4*2=8
3*2=6
x=6
120/6=20
