The domain of a relation is? A)the output (y) values of the relation
B)the input (x) values of the relation
C)a set of points that pair input values with output values
D) x and y values written in the form (x, y)

B) The input (x) values of the relation

In contrast, the range is the set of outputs (y) of the relation.

The set of all points (x,y) listed forms the relation itself. If you have any points that repeat an x value, but the y value is different, then the relation will not be a function.

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)
