At noon three students, Abby, Ben, and Cassie, are standing so that Abby is 100 m west of Ben and Cassie is 160 m east of Ben. While Ben stays in his initial position, Abby begins walking south at a constant rate of 20 m min and Cassie begins walking north at a constant rate of 41 m min . In how many minutes will the distance between Cassie and Ben be the twice the distance between Abby and Ben?

step-by-step explanation: 4 cause 2+2=4

7.3

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)
