1. write the equation of a line in slope intercept form that is perpendicular to the line y = –4x and passes through the point (2, 6). 2. k is the midpoint of segment ab. if segment ak = 3x+1 and segment kb = 1/3x + 9, find the length of segment ak. 3. j is the midpoint of segment kl. the coordinates of j are (-8,7) and the coordinates of k are (3,4). find the coordinates of l. @ttking40

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)
