Sample Response: Both are correct. As long as inverse operations and the properties of equality are used properly, both methods will generate the same solution. They both isolate the variable on one side of the equation.
Answer:
92
Step-by-step explanation:

Answer:
r = 11 makes 2r - 7 = 15 true.
Step-by-step explanation:
2r - 7 = 15
Add 7 to both sides.
2r = 22
Divide by 2.
r = 11
Proof:
2r - 7 = 15
2(11) - 7 = 15
22 - 7 = 15
15 = 15

Answer:
leading coefficient is 8
degree of the leading term is 4
degree of the polynomial is 4
Step-by-step explanation:
Given

Solving (a): The leading coefficient
This is the coefficient of the
with the highest power.
The highest
in the
is 5.
Hence, the leading coefficient is 8
Solving (b): Degree of the leading term
First, we identify the
term, i.e. the term that has the
.
This term is: 
So, the degree of the leading term is 4
Solving (c): Degree of the polynomial
This is the same as the
of the
term
So, the
of the
is 4
