Those are the only one I know, sorry :/
Answer:

Step-by-step explanation:
we are given that

since m is greater than or equal to 0 it's a positive number therefore, the square root of m is defined and recall that √x²=|x| thus

remember that,|a|•|x|=|ax| hence,

and we're done!

Answer: 15 ; (g^5) - h
Step-by-step explanation:
- To find 15% of 100, multiply 100 and 15/100. The 100's get crossed out and the answer is 15.
- The expression is (g^5) - h.
We are given

We can write it as

we can see that 2y is in first two terms
and -8 is in last two terms
so, we can factor it out

now, we can see that x+4 is common in both terms
so, we can factor it out

we can see that
x+4 is one of factor of terms
so, option-B..........Answer
