Option: B is the correct answer.
B. The number of excluded values of a rational expression cannot exceed the degree of the denominator.
<h2>Step-by-step explanation:</h2>We know that a rational expression is a expression of the form:
where p(x) and q(x) are polynomials.
Excluded value--
The excluded value of a rational expression are the values where the denominator of the expression is zero.
Also, the number of zeros of a polynomial is always less than or equal to degree of the polynomial.
Hence, the number of excluded values of a rational expression cannot exceed the degree of the denominator.
The answer is:
Option: B
Alright, lets get started.
The ages of all four sisters will be = x, x+2, x+4, x+6
As per given in question, two times of youngest sister age exceeds the oldest sister age by 30 means
Simplifying the equation
So this is the age of youngest sister.
So, age of oldest sister will be
Hene the age of oldest sister is 42 years. : Answer
Hope it will help :)
