do: first of first bracket x first of 2nd bracket
+( first of 1st bracket x 2nd of 2nd bracket)
+(2nd of 1st bracket x 1st of 2nd bracket)
+ (2nd of 1st bracket x 2nd of 2nd bracket)
== 10n -16n +20n+32= 14n+32
Answer:
C
Step-by-step explanation:
To solve, use inverse operations:

Now we solve for both +/- 7.
x+6=7
x=1
x+6=-7
x=-13
D.dilation changes the size is your answer. Hope this helps!
The answer is A) <span>Increasing: x < 7; decreasing: x > 7</span>
