That is too many questions for one post. It would be much better if you posted one question at a time and made an attempt at an answer, so we can help you understand the concepts better.
We are not here to "do homework" or to take the place of reading the assignment.
<<1. what is the value of x2 when
x = 5? >>
If x = 5, than x 2 = 7.
The absolute value signs   then tell you to change the sign, since the number inside is negative. Thus
x2 = 7 
5.Solve,n=13
6.solve,x+7=3
9.why does the equation x6=2x3 have no solution for x=3?
10.use a number line to diagram the solution of the absolutevalue equation x3=5.then write the solution set to the absolutevalue equation.
13.solve the inequality 6x<12 OR 3x>15.?
14.solve, z+3=5.
19.a_is a graph made up of separate,disconnected points?
22. Determine the probability of rolling at least one odd number or a sum of 9 with two number cubes?
27.to build arianes house will take a constant number of individual work days.if a contraction crew of 15 people can build the house in 20 days,how mAny people does it take to finish the house in 5 days?
29.solve the system by substitution:3x+y=13.
2x4y=4
