Which of the following is true about the polynomial 3x^6 - 4 ? select all that apply. the polynomial is a binomial. the polynomial is written in standard form. the polynomial has three terms. the polynomial has a leading coefficient of 6.

Short The first 2 are correct. The last two are false.

Explanation
A
Bi means 2. There are two unlike terms in this example. It cannot be reduced further.

B
It is written in standard form. The highest power on a variable is written on the left and each power after that is chosen by next highest power all the way down to no power (or no variable).

6x^3 + 11x^2 + 300x + 9

Notice that the powers start out at 3 and go to  2 and then 1 and finally a pure number. The leading integers have nothing to do with how you order the terms in standard form if the powers are all different. In this case 6 11 300 and 9 have nothing to do with the order.

C
The polynomial has 2 terms not 3.

D
The example has a leading power of 6. It has a leading coefficient of 3.

If the diameter is 8 than the radius is 4 because 2r or 2*radius equals the diameter. 4*2=8. 8/2=4.
