Solve:
x +9
x2 – 5x + 6
<0

(-∞,-9) U (2,3)

Step-by-step explanation:

(x+9)(x²-5x+6) < 0

x²-5x +6

= x² -3x -2x +6

= x( x-3) -2(x-3)

= (x-3)(x-2)

Substituting

(x+9)(x-2)(x-3)

For x < -9

the term is negative

For x >-9 x<2

the term is positive

For x>2 x<3

the term is negative

For x>3

the term is positive

(x+9)(x-2)(x-3) < 0

(-∞,-9) U (2,3)

x= 149. 24+7=31. 180-31=149

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
