Gordon, June and Sushil share some sweets in the ratio 3:5:2. Gordon gets 42 sweets. How many did Sushil get?

28

Step-by-step explanation:

42/3 = 14

2 * 14 = 28

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)

using pemdas, (order of operations) you'll see the answer is 24.
