Answer:
first one should be SAS
second one should be the third choice
No a polygon only has 3 sides and 3 angles.
Simplify the first numerator first
-2(x+1)
-2x-2
Then you can set up an equation using cross multiplication
5(-2x-2)= 3x
Simplify and solve
-10x-10=3x
-10=13x
-10/13=x
Final answer: x=-10/13
You just have to combine like terms here
6+7n^3 is the final answer
Answer:
13x3= 39
Step-by-step explanation:
10x3=30
3x3=9
30+9=39
