Brandon owes his brother $100. He will repay his brother $5 each week. Which expression gives the amount in dollars Brandon will still owe his brother after n weeks? 5−100n

100−5n

5n−100

100n−5

100-5n

Step-by-step explanation:

For example:

Week 1: 100-5(1)= $95 left

Week 2: 100-5(2)= $90 left

Week 3: 100-5(2) $85 left

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)
