Step-by-step explanation:
7. The ratio of two polynomials is written as a fraction so the correct answer is D. .
8. A rational algebraic expression with a monomial in the numerator and a binomial in the denominator is C. .
9. The best illustration for speed is so that will be D. .
10. The part of activity Vince can be completed by Vince after 4 hours is defined by A. 4x.
11. The value of x that will make the expression is -1.
If x = -1 then = = = = = 0 it is undefined since any number divided by 0 the quotient is undefined.
12. The correct representation for the phrase is A. .
13. The correct representation of the phrase is A. .
