Answer:
See the attachment
Step-by-step explanation:
7. The common difference is 4, so the next term will be 17+4 = 21, and the term after that will be 21+4 = 25. Figuring the next two terms as 21, 25 is sufficient to select the appropriate answer.
8. The table entry (0, 14) tells you only choices G and J are viable. The difference between terms of 22-14 = 8 tells you the appropriate choice is the one with a slope of 8, choice G.
9. In a linear equation, the sum of exponents of the variables in any/every term must not be greater than 1. (All exponents must be integers, as they are here.) Selections A and D have squared terms, so are not linear. Selection C has the product of variables "xy", so is not linear.

Answer:
The x's cancel so definitely is choice C: 1/9
Step-by-step explanation:
We have root( 1/(x^2) ) * root ((x^2) / 81)
simplifying this we get as follows:
root( 1/(x^2) ) * root ((x^2) / 81)
= *
= ( 1/x ) * (x/9)
the x's cancel
= 1/9
choice C 1/9
