A student simplified the rational expression using the steps shown.

(x^2/5*x^4/5/x^2/5)^1/2=x^6/5/x^2/5 )^1/2=(x^3)^1/2=x^3/2
Is the answer correct? Explain.

35 is an outlier

step-by-step explanation:

ratio is 2 : 9

the answer is three

13.5 : 3

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
