I believe it is congruent
1.= 6,391
2.=6,3910
3. = 6,39100
All you do is add the 0s at the end
Step-by-step explanation:
Step 1: -x^2 is -1 because x is always 1.
Now that you found your first step take -1x+10=6. You're going to subtract 10 from both sides which leaves you with a sum of -4. So -1x= -4 now divide -4/-1x which gives you a positive number.
Answer: The answer here is x=2
Step-by-step explanation:
This is a linear equation, take 5x to other side ut will change a sign then solve for x.
2x+5=21
2x=21-5
2x=16
Lastly divide by 2 both sides to get 2
