Question

An expression of the fifth degree is written with a leading coefficient of seven and a constant of six. Which expression is correctly written for these conditions? 6x5 + x4 + 7 7x6 − 6x4 + 5 6x7 − x5 + 5 7x5 + 2x2 + 6

Answer 1

7x^5 + 2x^2 + 6

Explanation:

"Fifth degree" means there will be a term with an exponent of 5 and that will be the largest exponent in the expression.

"Leading coefficient of 7" means the highest-degree term will be 7x^5.

"A constant of 6" means the lowest-degree term will be +6.

The description means the expression will look like ...

7x^5 + <terms of lower degree> + 6

The answer choice shown above matches this description.
