Apply distributive property to factor out the gcf 27+18r=

9(3 + 2r)

Step-by-step explanation:

      27                     18r

       ∧                       ∧

    3  9                    2  9r

         ∧                         ∧

        3  3                     3 3r

27: 3 * 3 * 3

18r: 2 * 3 * 3 * r

Common Factors are 3 * 3 = 9

27: 9 * 3

18: 9 * 2r

27 + 18r  =  9(3 + 2r)

step-by-step explanation:

thats the first half

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
