time 2nd 5/5 it become 35/5x-20
2/5x-20+35/5x-20
=37/5x-20
Answer:
Step-by-step explanation:
Well it's really simple honestly if you take you time and read the sentence you see that it's missing the GREATEST part
1) The given expression 7x^4 + 5x^2 + x - 9 is a polynomial.
2) The given expression 7x^6 - 4x^3 + 1/x is a trinomial.
<u>Step-by-step explanation</u>:
1) 7x^4 + 5x^2 + x - 9
- The number of terms in the above expression is 4.
- An algebraic expression with more than 3 terms is known as polynomial.
- <u>The degree is the power of the x term in a expression</u>
- first term = 7x^4 has a degree of 4.
- second term = 5x^2 has a degree of 2.
- third term = x has a degree of 1.
- fourth term = 9 is a constant term with no degree.
2) 7x^6 - 4x - 1/x
- The number of terms in the above expression is 3.
- An algebraic expression with 3 terms is known as trinomial.
- first term = 7x^6 has a degree of 6.
- second term = 4x has a degree of 1.
- third term = 1/x has a degree of -1.
Answer a because if you replace the x with -1,0, and 3, you will get 5,1,and 37.
