Answer:
All three operations lead to polynomials.
See explanations below.
Step-by-step explanation:
Polynomial a = 
Polynomial b = 
Therefore:
a + b = 
where we have combined all like terms. This is clearly another polynomial (of grade 2)
a - b (here we need to flip all signs inside the parenthesis when we remove this grouping symbol):
which is clearly another polynomial (but of grade 3)
a * b : (here we use distributive property to multiply each term of the first polynomial by each term of the second one, and then combine like terms)
which is indeed another polynomial (this time of grade 6)

Answer:
7.3
Step-by-step explanation:
In order to find the hypotenuse, we just need to use the Pythagorean Theorem.
Remember, that this theorem only works for right triangles.
This theorem states that a^2+b^2=c^2
This is where a and b are legs of the triange, and c is the hypotenuse.
Knowing this, we can plug our values in.
6.4^2+3.5^2=c^2
Simplify.
41.344+12.25=c^2
53.594=c^2
Root both sides.
c=7.32 (about)
Round that to tenths.
c=7.3

Answer:
104 14/15
Step-by-step explanation:
15 goes into 1574 104 times and you have 14 remaining so you have 104 with a remaining fraction of 14/15.
