Answer:

Kindly check explanation

Step-by-step explanation:

Organizations like NASA who explore space and planets often have to deal with measurement of very long distances such as the one stated above. The Major challenge with the distance written in the format expressed above is the difficulty to read, state or use in mathematical calculations as it is too explicit. A more effective method is to express this distance in standard format and more suitable long distant units such as miles.

For instance;

880,000,000,000,000,000,000,000 kilometers could be expressed as in standard form as ;

8.8 * 10^23 km

PLEASE HELP!!! THIS IS MY LAST QUESTION!! ASAP!!
aleksandr82 [10.1K]

Answer:

In order of what is shown on the pic:

- Trinomial

- Monomial

- Trinomial

- Binomial

- Polynomial with four terms

Step-by-step explanation:

Again, in the same order as above:

1. The first has three terms, making it a trinomial

2. 7x^2 - 7x^2 +4x

The 7x^2 cancels out and we are left with only 4x

Since there is one value, it is a monomial

3. This one has three terms, making it a trinomial

4. This one has two terms, making it a binomial

5. The last one has four terms, making it a polynomial with four terms.
