Step-by-step explanation:

11 1/5 ÷ 2 3/4

Change to improper fractions

(5*11 +1)/5 ÷ (4*2+3)/4

56/5 ÷ 11/4

Copy dot flip

56/5 * 4/11

The exact answer is

224/55 or 4 4/55

To estimate

Change the 56 to 55

55/5 *4/11

11*4/11

Canceling the 11's

4

Since we rounded the numerator down just a little, our estimate is a little low

45

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)
