Answer:
Beatrice age = 34 years
Step-by-step explanation:
Given:
Andrew age = Beatrice age + 2 year
Chris age = Beatrice age - 3 year
Sum of Andrew's age and Chris' age = 67
Find:
Beatrice age
Computation:
Assume;
Beatrice age = b
So,
Andrew age = Beatrice age + 2 year
Andrew age = b + 2
Chris age = Beatrice age - 3 year
Chris age = b - 3
So,
Andrew's age and Chris' age = 67
b + 2 + b - 3 = 67
2b - 1 = 67
2b = 68
b = 34
So,
Beatrice age = b
Beatrice age = 34 years
Answer:
D
Step-by-step explanation:
x=(-4(plus minus)sqrt(4^2-4*2*(-1))/2*2
x=(-4(plus minus)sqrt(16+8))/4
x=(-4(plus minus)sqrt(24))/4
x=(-4(plus minus)sqrt(2*2*6))/4
x=(-4(plus minus)2*sqrt(6))/4
x=(2(-2(plus minus)*sqrt(6)))/2*2
x=(-2(plus minus)*sqrt(6))/2
x=(-2+sqrt(6))/2
x=(-2-sqrt(6))/2
(Option 4 I think, but can see for sure)
