Question

Find with distance formula :

1) Q = (2 , 8 ) , R = (1,2)
( ----- )
( 5 )


2) A = (0,2) , B = ( 1 , 0.5 )​

Answer 1

Answer:

Factorise

6(2a - b) - 15(2a - b)^2

(x + y) - (x + y)^2 + (x + y)^3

ab(x^2+y^2)-xy(a^2+b^3)

Step-by-step explanation:

Factorise

6(2a - b) - 15(2a - b)^2

(x + y) - (x + y)^2 + (x + y)^3

ab(x^2+y^2)-xy(a^2+b^3)

Answer 2

Answer:

1) QR = root 37

2) AB = root 3.25

Step-by-step explanation:

Distance formula = root of (x2-x1)² + (y2 - y1 )²

1) QR = root of (2-1)² + (8-2)²

= root of (1)² + (6)² = root of 1 + 36

= root 37

2) AB = root of (1-0)² + ( 2 - 0.5)²

= root of (1)² + (1.5)² = root of 1 + 2.25

= root 3.25
