(3k+4)(9k+5) the answer should be a polynomial in standard form

27k^2+51k+20

Step-by-step explanation:

Distribute the 3k to both 9k and 5. Then distribute 4 to the 9k and the 5. When you multiply the 3k and 9k it gives you the 27^2. 3k times 5 gives you 15k. 4 times 9k is 35k. 4 times 5 is 20. Combine like terms. 15k plus 35k is 51k. When put in order you get the above answer!

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
