you are given the steps for using a compass and a straightedge to construct a line perpendicular to a given line through point a not lying on the given line. arrange the steps in the proper sequence

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

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)

it is 10.6 according to my calculations

thus, the first answer choice, y = sec x, is the correct one
