Which of the following is equivalent to (x2 − 9)(x + 2) − (x2 + 4x + 4)(x − 5)? Select one:
A. 3x2
B. 3x2 + 2
C. 3x2 - 13x + 2
D. 3x2 + 7x + 2

answer: b.48 for

step-by-step explanation:

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 )

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
