The distance between the two points (-1, 4) and (5, 4) is 6 units.
<u>Step-by-step explanation:</u>
The given Coordinate points are (-1, 4) and (5, 4).
The points are considered as (x1,y1) and (x2,y2).
Here,
x1 = -1 and x2 = 5
y1 = 4 and y2 = 4
<u>The distance formula is given by :</u>
Distance =
<u>To find the distance between these two points :</u>
The distance formula is used,
Distance =
⇒ √(6)²
⇒ √36
⇒ 6
Therefore, the between the points is 6 units.
<u>Answer: </u>
Simplified form of given expression (2x – 9 )( x + 6 ) is
<u> Solution: </u>
We need to simplify following expression.
(2x – 9) ( x + 6)
For sake of simplicity lets first assume 2x – 9 = A
So expression becomes A(x+6)
= Ax + A6
Now replace A by 2x – 9
= (2x – 9 ) x + (2x – 9 ) 6
On simplification, we get
Hence simplified form of given expression (2x – 9 )( x + 6 ) is
