A. quadratic

Step-by-step explanation:

Change in x      3       2       Change in y

6 - 3 = 3             6      3          3 - 2 = 1             Change in differences

9 - 6 = 3             9      6          6 - 3 = 3               3 - 1 = 2

12 - 9 = 3          12      11          11 - 6 = 5               5 - 3 = 2

15  12 = 3          15      18         18 - 11 = 7              7 - 5 = 2

The changes in x are all equal, 3.

The changes in y are not equal, 1, 3, 5, 7. This is not linear.

The changes in the differences in y are equal, 2. This is quadratic.

answer are

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)
