I don't quite understand the ten strategy, or what EXACTLY you're asking. But, what you can do is when you add a one digit number plus a nine, just change the nine to a ten and subtract one. It is very easy. So, 7+10 equals 17, subtract one and you get 16 which is 7+9. It is always one less than anything plus 10.
1. There is no "h" in f(x) = log(x). The question is nonsense.
2. The log function is defined for arguments greater than zero. You're probably expected to select D, though A and B could also be correct.
3. Same deal. The log function is defined for x > -2, but the domain could be restricted to x > 2. You're expected to select FALSE.
4. Same deal. Choose B, though D is also correct.
5. C is the proper choice. (See discussion of the log function, above.)

Answer:
The answer is:
She used the wrong common denominator
Step-by-step explanation:
Solving the given equation
Lets consider the steps given in the question:
Lets compare both solutions:
In the original solution, the denominator of first term is (x-2)(x-3)
In the solution given in the question, the denominator of first term is (x-2)(x+3).
So the mistake she did in step 2 was that she change the sign of 3 in (x-3) from negative to positive, due to which she gets the wrong common denominator shown in Step 3.
Answer:
The with and length of the original rectangle are:
width: 20 ft
Length: 30 ft
Step-by-step explanation:
Lets check
Yes, 30 is 10 longer then 20,
the area of the original is 600
if it was 40 and 30 then it would equal 1200
