Consider the rational expression.
1 answer:
Answer:
The options 1,2 and 4 are correct.
Step-by-step explanation:
The given rational expression
From the given expression it is noticed 12 is a term in both the numerator and denominator. Option 1 is correct.
The denominator has 3 terms. Option 4 is correct.
From the above expression it is clear that (x+2) is a factor of the numerator. Option 2 is correct.
Therefore options 1,2 and 4 are correct.

Answer with explanation:
Property of Quadrilateral A B CD
⇒Equation of Line AD is, y= -3 x.
⇒Equation of Line BC is, y= -3 x +11
Coordinates of CD = C(2,5) and D(-1,3)
Equation of line CD will be
Equation of line AB will be, which is parallel to CD, as opposite sides of parallelogram are parallel and equal,is equal to
2 x -3 y + k=0
Because when lines are parallel their slopes are equal.
→→Equation of line AD is , y= - 3 x.
Coordinates of point A can be calculated by
→2 x -3 × (-3 x ) +k=0
→2 x +9 x +k=0
→→→Similarly, Coordinate of point D can be calculated by solving these two lines:
y = -3 x + 11
2 x -3 y + k=0
→2 x -3 × (-3 x +11) +k=0
→2 x +9 x -33 +k=0
→11 x =33 -k
→→Coordinates of A is
Coordinates of Point D is .
you, can get infinite number of ordered pairs, for different value of k.
For, k=0 ,
A= (0,0)
D=(3,2)
