What is the product of positive integers a and b such that 1 /a + 1 /b + 1 /ab = 1?

throw the computer

step-by-step explanation:

i believe it's a.

i'm not sure on this one, most likely correct.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

yes.. it's proven to be 36.
