Step-by-step explanation:
ok so for number 1 you first have to group the like terms therefore you will now have:
9r-4r+8-6
and now you calculate:
9r-4r=5r
8-6=2
so that means 5r-2 is simplied version for no.1
for number you 2 you first multiply why is inside the brackets by what is in the outside:
2(x+3y)
2x+6y (simplified version)
hope this helps! no problem

Answer:
∠Y = 55°
Step-by-step explanation:
Complementary angles have a sum of 90°.
∠S + ∠Y = 90°
(5∠Y -240°) +∠Y = 90°
6∠Y = 330° . . . . . . . . . . . . add 240°, collect terms
∠Y = 55° . . . . . . . . . divide by 6
