Answer:
Step-by-step explanation:
Let b is the age of the brother and s as the age of the sister.
It is given that if four times the brother's age is subtracted from three times the sister's age, the difference is 8.
We need to find an equation for the given statement.
Four times the brother's age = 4×b = 4b
Three times the sister's age = 3×s = 3s
Four times the brother's age is subtracted from three times the sister's age.
The difference is 8.
Therefore, the required equation is .
It is 2 because 3x2x2 equals 12

CA must be in the range [15 - 9, 15 + 9] = [6, 24]
For the line segments to form a triangle the length of CA cannot be less the the difference between the other sides or greater than their sum.
At either extreme the three points A, B and C will be co-linear thus forming a triangle with area of zero
