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:
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

Simplifying the expression so, there is only one power of each base we get
Option D is correct answer.
Step-by-step explanation:
We need to simply the expression so, there is only one power of each base.
Solving:
We can write it as:
Now using exponent rule:
Now using the exponent rule: the bases should be same
So, simplifying the expression so, there is only one power of each base we get
