find the product of (2x − 3)(2x2 + 7x − 1).
a. 4x3 − 6x2 − 9x + 3
b. 4x3 + 8x2 − 23x + 3
c. 4x3 + 20x2 − 9x + 3
d. 4x3 − 6x2 − 23x + 3

4x^3-6x^2-9x+3

Step-by-step explanation:

Multiplying the two will be

4x^3 + 14x - 2x - 6x^2 - 21x +3. Add them together and you have your answer

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.
