Answer:
x³ - 3x² - 18x
Explanation:
Before we begin, remember the following:
xᵃ * xᵇ = xᵃ⁺ᵇ
Now, for the given:
To solve thus question, we will simply multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final answer.
This can be done as follows:
(x + 3)(x² - 6x)
x(x²) + x(-6x) + 3(x²) + 3(-6x)
x³ - 6x² + 3x² - 18x
x³ - 3x² - 18x
Hope this helps :)

24. This answer would be A, or y=x^4. When the exponent is used, in each ordered pair, every time x is increased by 1, y is multiplied by 4, like in every exponent. 1 x 4 = 4. 4 x 4 = 16. 16 x 4 = 64. 64 x 4 = 256.
25. The answer is C, or C(n) = (0.90 + n) - 0.40. Your coupon subtracts 40 cents off of your total amount of cans of tuna, but the amount of tuna cans that you will buy is not stated, so that unknown number is n.
