The polynomial has 3 terms and a degree of 10.

Step-by-step explanation:

The given polynomial:

Here, two terms and have same power for s and t i.e. they are like terms.

Combine like terms , we get

i.e. there are 3 terms.

Degree of  is 1+9=10;

Degree of is 6+2=8;

Degree of    is 7.

Since degree of the polynomial = highest degree i.e. 10

Hence, the polynomial has 3 terms and a degree of 10.

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
