A polynomial is written correctly when the exponents are listed in order from highest to lowest.  The highest exponent then dictates the degree of the whole polynomial.  The first choice above is written in standard form from highest degree to lowest.   Doesn't matter that we might skip the x-squared term or any other x-term, as long as they're in order from highest to lowest.  The degree on that first polynomial, the one you're after, is 4 because that's the highest exponent, and there are 4 terms there.  Terms are "bunches" of numbers and variables stuck together by multiplication and separated by + or - signs.

Randy rented a rectangular storage shed with the volume of 357 ft does it sheds height is 8 and 1/2 ft and the width of is 6 ft
ollegr [7]

Answer:

7 feets

Step-by-step explanation:

Volume of shed, V = 357 feet³

Height of shed, H= 8 1/2 fts

Width of shed, W = 6 ft

Using the relation :

Volume = Length * width * height

357 = L * 6 ft * 17/2 feets

357 feets³ = L * 51 feets²

L = 357 feets³ / 51 feets²

Length, L = 7 feets
