It helps when you count decimal places to line up the numbers
First, you must know the meaning of the words used in the problem. For example, what is the definition of a constant term?
constant term: a number of a fixed value that is unaccompanied by a variable.
For example:
Y= 2x +7 (in this example "7" is the constant term because its value cannot be changed by any variable)
I would argue that, because every term is followed by an "x" in this equation, there is no constant term unless you were allowed to factor out an "x" from every term in the equation. However, then the equation would no longer be in standard form.
Does this make sense?
When simplified the answer is -2n^3+13
By the Pythagorean Theorem, the lengths of the sides of a triangle satisfy if the triangle is a right triangle (in which case the angle between sides a and b is the right angle).
I do believe it is the thrid one.
