Rectangle ABCD has coordinates A(-10,5), B(10,5), C(10,0), and D(-10,0). Rectangle A’B’C’D has coordinates A’(-10,-5) B’(10,-5), C’(10.0) and D’(-10,0). rectangle A”B”C”D has coordinates A”(-2,-1) B”(2,-1) C”(2,0), and D”(-2,0)

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)
