15%

Step-by-step explanation:

RS. 6450 = 15%

6450 percent *15 =

(6450:100)*15 =

(6450*15):100 =

96750:100 = 967.5

monthly income=rs14000

annual income =rs14000×12=rs 168000

since it is greater than rs125000

he needed to pay tax=x% let

tax amount =6450

x% of rs (168000-125000)=6450

x/100×43000=6450

x=6450/430=15

therefore required tax %=15%

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)
