You need to expand the brackets before you can simplify, so:
-3 × 10x = -30x
-3 × 4y = -12y
6 × 6x = 36x
6 × -2y = -12y
So now you have (-30x - 12y) + (36x - 12y)
-30x + 36x = 6x
-12y + -12y = -24y
So your answer is 6x - 24y. I hope this helps!
Answer:
x = -9 x = 1/4
Step-by-step explanation:
(x+9)(4x-1)=0
Using the zero product property
x+9=0 4x-1=0
x= -9 4x =1
x = 1/4

Answer:
The common difference is -20
Step-by-step explanation:
Simply subtract 5 from -15
-15-5 = -20
The answer would be 10.
6 + 5 = 11
11 x 9 = 99
This means 9(6+5) = 99
99 - 89 = 10
