Answer:
x = -3.5
Step-by-step explanation:
3 x 2 + 2x + 1 = 0
6 + 2x + 1 = 0
2x + 7 = 0
2x = -7
x = -7/2 = -3.5

Let the age of Jen 2 years later be x,
age of jack two years later = 2x
total age of jack and jen now = 2x + x - 2 - 2
= 3x - 4
3x - 4 = 66
3x = 70
x = 70/3
= 23.3 (to three significant figures)
age of jen now = x - 2
= 23.3 - 2
= 21.3
Jen is 21.3 years old now.

The answer: Tom will get 166£ and Ben will get 581£
The solution and explanation: since we need to share the money in the ratio 2:7, we see the number of total parts of money that we will have is 9. Because 7+2=9 so we will have 9 parts of which we will give 2 parts to Tom and 7 parts to Ben.
Step by step:
Step one: we divide 747 by nine to get the amount of money included in one part. 747:9=83
Step two: we multiply 83 by 2 to find out how much money will Tom get
83•2=166
Step three: we multiply 83 by 7 to find out how much money will Ben get
83•7=581
