Mr. Walker gave his class the function f(x) = (x + 3)(x + 5). Four students made a claim about the function. Each student’s clai
m is below. Jeremiah: The y-intercept is at (15, 0). Lindsay: The x-intercepts are at (–3, 0) and (5, 0). Stephen: The vertex is at (–4, –1). Alexis: The midpoint between the x-intercepts is at (4, 0). Which student’s claim about the function is correct? The claim by is correct.
A regular polygon with each interior angle of 170 deg will have each exterior angle as 180–170 = 10 deg. Hence the number of sides in the regular polygon = 360/10 = 36 sides.
