a salesman sells a car for $11,000. if he is paid a commission of 4.5% for the first $10,000 and 7.5% on the reminder, then the he receives is​

$525

Step-by-step explanation:

First you calculate 4.5% of $10000

=$10000÷100x4.5

=$450

Then you calculate the 7.5% of the reminder (which is $1000)

=$1000÷100x7.5

=$75

Now you add the two answers

$450+$75

=$525

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)
