For this case, we have the following equation of the second degree:
If we divide between 2 on both sides of the equation, we will have:
Where:
The solutions will come from:
Substituting:
So, we have:
Answer:
Option A
Option E
Answer:
Step-by-step explanation:
First use distributive property
3(4x-2) = 12x-6
5x+9=12x-6
Now use property of equality
5x+9=12x-6
-9. -9
5x=12x-15
-12x -12x
-7x= -15
-7x divides by -7
-15 divided by -7
Answer: x= 15/7 or x= 2.143
Answer:
x=14
Step-by-step explanation:
The interior angles of a regular decagon are the same and add up to 1440.
10(10x+4)=1440
4/500=0.008
scientific notation form = 8 x 10^9
