Answer:
11. (x-2)/(x+8)
12. 9+t
13. h = 2A/b
Step-by-step explanation:
11. Since x is used to represent the number, 2 less than a number is x-2. 8 more than a number is x+8. The quotient of the first and second of these is the first one divided by the second one:
... (x -2)/(x +8) . . . . . parentheses are required unless the expression is typeset:
![\dfrac{x-2}{x+8}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx-2%7D%7Bx%2B8%7D)
12. Apparently, we're to assume the salesman keeps on driving. If he had any sense (or a good union), he would stop after 9 hours. t hours added to 9 is ...
... 9 + t
13. Divide by the coefficient of h.
... h = A/((1/2)b) = 2A/b

Answer:
area = 8(x + 6)
The distributive property says that the x must be added to the 6 before it is multiplied by the 8
