Use the discriminant to determine the nature of the roots of the following equation. x2 + 2x + 5 = 0 double root real and rational root real and irrational root non-real root

no not all of them.

step-by-step explanation:

some of them have a square base.

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.
