A car rental charges $9.50 an hour plus rental fee of $32.50. How much is the total charge for 16 hours?

$184.5

Step-by-step explanation:

so we know they are charging x hours for renting plus a flat rent fee of 32.5

r(x)= 9.5 x + 32.5

r(16)= 9.5 (16) + 32.5

r(16)= 152+ 32.5

r=$184.5

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)
