Watermelons are on sale for $3 each, but customers can buy no more than 4 at this price.
For watermelons bought at the sale price, the total cost, y, is directly proportional to the number bought, X .This function can be modeled by y=3x.
What is the domain of the function in this situation?
OA. Al positive numbers, x >0
OB. (0, 3, 6, 9, 12}
Oc. (0, 1, 2,3, )
O D. 0, 1, 2, 3, 4}

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

-81 -56 -27 0 81
