30 points! can anyone me in number 9 and 10? ? you! : )

Step-by-step explanation:

9. 66 in , 5.5 ft, 1 yd and 8.3 in

10. Not sure about 10 it doesn’t give me all the info to answer

11. 3ft in 1 yard. If there is 3 yards the there is 9 feet. Plus the other 2 feet. So you have 11 ft and there is 12 inches in a foot so you multiply 11ft by 12 inches leaving you with 132 inches in 3 yards and 2 feet

alright well the answers to your question is

2xy/9 hope this have a nice day : )

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)
