2(-n-3)-7(5+2n)
First, you need to distribute the numbers in front of the parentheses to those in the parentheses. This means you multiply.
2 times -n= -2n
2 times -3= -6
-7 times 5= -35
-7 times 2n= -14n
This leaves you with
-2n -6 -35 -14n
Next, combine like terms.
(-2n) + (-14n)= -16n
(-35) + (-6)= -41
This gives you
-16n-41, which is B in your answer choices.
Hope this makes sense!! :)
On the X side it’s +1
Hopefully this helps
Suppose you roll a red number cube and a blue number cube. What is the probability that you will roll a 5 on the red cube and a 1 or 2 on the blue cube?
Answer:
Correct, it is 15
Step-by-step explanation:
Because 3 turns into 9, you also want to multiply the other by 3, so you’d do 5x3 to get 15
