Answer:
6
Step-by-step explanation:

The exponents of x (in the order the polynomial was given) are: 3, 0, 5, 2
Now we put the exponents of x in descending order.

The second term is 
The degree of a term is the sum of the exponents of all variables of the term. The exponent of x is 3. The exponent of y is 3, and 3 + 3 = 6.
The degree of the second term is 6.
Answer: 6
644 is 80% of the regular price, so price=644/0.8 = 805 $

Debug the following:any one free out
sin theta equals to cos theta then the value of sin 2 theta
<h3>The solution is (x, y) = (3, -24)</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
-3x - y = 15 -------- eqn 1
y = -8x ------ eqn 2
We have to find solution of (x, y)
We can solve by substitution method
<em><u>Substitute eqn 2 in eqn 1</u></em>
-3x - (-8x) = 15
-3x + 8x = 15
5x = 15
Divide both sides by 5
<h3>x = 3</h3>
Substitute x = 3 in eqn 2
y = -8(3)
<h3>y = -24</h3>
Thus solution is (x, y) = (3, -24)
