The lengths of two sides of a triangle are shown below: Side 1: 3x2 - 4x - 1
Side 2: 4x - x?.5
The perimeter of the triangle is 5x3 - 2x² + 3x - 8.
Part A: What is the total length of the two sides, 1 and 2 of the triangle? (4 points)
Part 8: What is the length of the third side of the triangle? (4 points)
Part C. Do the answers for Part A and Part B show that the polynomials are closed under addition and subtraction? Justify your answer.

Hmm

Step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
