2.1 x 2.1 -0.9 x 0.9
a)
2.1 -0.9

3.6

2.1(2.1) - 0.9(0.9)

4.41 - 0.81 = 3.6

1/3 + 1/5 = 8/15.

step-by-step explanation:

hope it

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
