For f(x)=2x+1 and g(x) =x2-7, find (f*g)(x)

  (f×g)(x) = 2x³ +x² -14x -7

Step-by-step explanation:

(f×g)(x) = f(x)×g(x) = (2x +1)×(x² -7)

  = 2x(x² -7) +1(x² -7)

  = 2x³ -14x +x² -7

(f×g)(x) = 2x³ +x² -14x -7

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
