If b=17 in and c=8 in, then what is the measure of a?

Answer this question! 30 points and brainliest!

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)

Y+ 2/y is it a polynomial in one variable or not? and if so, why?
