Examine Carmen’s plans for rail lines at a train station. Parallel lines k and l are crossed by transversal t. Line m crosses lines t, k, and l. The angles formed by lines k, t, and m, clockwise from top left are 2, 1, blank, blank, blank (6 x + 5) degrees; formed by lines l and t are blank, (7 x minus 4) degrees, blank, blank; formed by lines l and m are 48 degrees, blank, blank, blank. What is the measure of angle 2?

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply
