Open-Ended Write an equation to represent the following description. Use pencil and paper. Describe a real-world situation the equation could represent.
Eighteen less than four times a number is – 15.
Choose the correct answer below.
OA. 4x + 18 = - 15
OB. 18x - 4 = - 15
OC. 4(x - 18)= - 15
OD. 18x + 4 = - 15
W
OE. 4x - 18 = - 15

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)
