O B. 4x4 + 9x3 - 8x2 + 15x
O C. 24 - 9x3 – 8x2 + 15x
O D. 2A - 9x2 - 9x2 - 15x

Step-by-step explanation:

2x^4+x^3-3x^2-10x^3-5x^2+15x

2x^4-9x^3-8x^2+15x

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.
