The equation for this would be:
y+6= 1/5(x+7)
2 :3 :4 gives 9 shares (2 + 3 + 4)
9 shares = 120cm
1 share = 120/9 cm = 13 1/3 cm ( or 13.333)
2 shares = 26 2/3 cm
3 shares = 40 cm
4 shares = 53 1/3 cm
The answer is 19.6 cm^2
you should find the height of the triangle by heron formula: it will be 9.8
so the area is

good luck
Answer:
Step-by-step explanation:
Given that there are 3 events as
rolling 3 dice, are the events A: sum divisible by 3 and B: sum divisible 5
The sample space will have
(1,1,1)...(6,6,6)
Sum will start with 3 and end with 18
Sum divisible by 3 are 3,6,9..18
Sum divisible by 5 are 5,10,....15
The common element is 15
Hence these two events are not mutually exclusive.
