The first one is the second one is All real numbers Step- by-step explanation:
1. Anything raised to the " zeroth" power is always 1
2. Because 7 is being raised to the zeroth power, the number inside the parentheses becomes 1. Now x can equal anything, 1 times itself will always equal 1, no matter how many times you multiply them.
Answer:
1) Cubic
2) 2
3) -3
4) 
5) 
Step-by-step explanation:
The given polynomial is:

The degree i.e. the highest exponent of the variable involved is 3. So the polynomial is a Cubic polynomial.
The terms in a polynomial can be distinguished by addition and subtraction symbols. So, for the given polynomial there are 2 terms.
The constant term is the term without any variable. So the constant term in given polynomial is -3.
Leading term is the term with variable having highest exponet which defines the degree of the polynomial. So leading term of the given polynomial is 
Leading coefficient is the coefficient of the leading term. So for given polynomial the leading coefficient would be 
Answer:
Step-by-step explanation:
36+88+y=180
124+y=180
y=180-124
<u>y=56</u>
x+90+56=180
x+146=180
x=180-146
<u>x=34</u>
