5. which polynomial is written in standard form for the polynomial below?
-7x^2 - x^3 + x^5 +2

a. x^5+x^3+x^5+2

b. x^5 - x^3 + 7x^2+2

c. -7x^2 - x^3 + x^5+2

d. 7x^2 + x^3 + x^5+2

C, D, D, B

Step-by-step explanation:

2. A polynomial has only integer exponents, no square roots.  So C is not a polynomial.

3. The degree of the polynomial is the sum of the exponents of the highest term.  p has an exponent of 1 and q has an exponent 4, so 1+4 = 5. D

4. Count the number of terms being added or subtracted.  p^3, 4pq^2, q^2, and -3q.  So there are 4 terms. D

5. Standard form of a polynomial is written from the highest exponent to the lowest.  So the answer is B.

if e is the midpoint of bd, then bd is 14.
