Answer:
B
Step-by-step explanation:
Look for an expression with (x - 5 ) as this will give zero when x = 5, that is
x - 5 = 5 - 5 = 0
The only expression with a factor of (x - 5 ) is B
Answer:
option a is the answer
Step-by-step explanation:
put the value of x in each expression as x = -2
you'll see that in option a the expression becomes

which is not defined. hence -2 is excluded value

Step-by-step explanation:
Answer: The ratios APBQ : APBC=4:21 and AAQP : AABC= 3:28
Explanation:
Here, ABC is a triangle where, P and Q are the midpoints of the edges AC and AB respectively,
Now, according to the question ,AP:PC=1:3 let AP=x and PC=3x where x is any real number. Thus, AC=AP+AC= x+3x= 4x
Similarly, AQ:QB=3:4 let AQ=3y and QB=4y where y is also any real number. Thus, AB=AQ+QB=3y+4y=7y
Since, 
And,
