Daniel runs a boat rental business near a small river. he charges 10 per boat rental and averaged 32 rentals in a day. he estimated that for every $1.00 increase in rental price he can expect the business to lose two rentals per day. let x represent the number of $1.00 increases in rental price.

no not all of them.

step-by-step explanation:

some of them have a square base.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

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.
