What is the cost of paving a driveway that is 15 feet wide and 24 feet long, if the cost of paving it is $50 per square foot; and there's a gap in the driveway that's 15 feet wide and 3 feet long
which does not need to be paved?

3,235

Step-by-step explanation:

beacuse the amount of work your doing tou you should be a gansta

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)
