Answer:
(-1,-1)
Step-by-step explanation:
Answer:
son's present age = 30
father's present age=60
Step-by-step explanation:
his son's present age = x years
his father's present age = 2x years
before 20 years his son's age=(x-20) years
before 20 years father's age=(2x-20) years4(x-20)=(2x-20)
4x-80=2x-20
4x-2x=80-20
2x=60
x=30
Question:
Factor 
(8 - x)(8 - x)
(8 + x) (8 - x)
(X + 8)(x-8)
Answer:
Option B:
is the factor
Explanation:
Given that the expression is 
We need to find the factor of the given expression.
Let us rewrite the expression as 
Since the expression is of the form
, let us use the identity 
where a = 8 and b = x
Substituting the values in the identity, then the expression can be written as

Thus, the factor of the expression is 
Hence, Option B is the correct answer.
