PLEASE HELP ME Which description is paired with its correct expression?
+8
o two less than the quotient of a number cubed and four, increased by eight: 2-
O six times the difference of five and a number squared; 6(x2-5)
CO
O three more than the quotient of nine and a number cubed, decreased by two; 3+
2
twice the difference of a number squared and three; 2n? - 3

1. perpendicular

2. parallel

3. perpendicular

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)

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
