the law of cosine is
c2 =a2+b2-2abcos(c)
Greatest vessel to fill each in exact number of times is 6 litres
Step-by-step explanation:
To solve this, we will find the greatest common factor of 36,18 and 72
Thus;
Their prime factors are;
18: 2, 3
36: 2, 2, 3, 3,
72: 2, 2, 2, 3, 3
The factors common to all of them are 2 & 3.
GCF = 2 × 3 = 6
-3x+6
-2x - 1 - x + 7
collect like terms and calculate:
2x-3=y
y=2*2-3=
y=4-3
y=1
