Answer:
(a) i and ii: 2b-2 = b+b-2
(b) i and iii: c+d = d+c
(c) ii and iii: a + 2b - 1 = a+b-1+b
(d) i and iii: x+(y-z) = x-(z-y)
(e) ii and iii: (a-1)² = (1-a)²
(f) i and ii: 3a-b-1-1 = 3a+b-2-2b

Answer:
565.2 in²
Step-by-step explanation:
2pi × r × (r + h)
2 × 3.14 × 5 × (5 + 13)
31.4 × 18
565.2
1 yr = 12 months
- 2931/12 = - 244.25 per month
4A = E , A=E/4-----(1)
B/4=E , B=4E-------(2)
C+4=E, C=E-4------(3)
D-4=E, D=E+4------(4)
Substitute all values in 5th equation,
A+B+C+D=100 = E/4 + 4E + E-4+ E+4 =100
E/4 + 6E = 100
25E = 400
E=16 ANS....
