correct me if im wrongg!!!
Answer:
An unknown variable
Step-by-step explanation:
r is an unknown variable -> the equation is used to solve for it.
Answer:
0
3
10
21
36
Explination:
0 x anything is still zero, but I don't know if that counts.
1 (2+1) = 3
2 (4+1) = 10
3 (6+1) = 21
4 (8+1) = 36
|a| = b gives
a =b or a = -b
so,
|-x| = -10
gives
-x = -10 or -x = 10
x = 10, -10
now let us verify,
when x = 10, |-10| = +10 and it is not = -10
so, x= 10 is NOT a solution.
when x = -10, |-(-10)| = |10| = 10 and it is not = -10
so, x= -10 is NOT a solution.
hence, this equation does not have a solution.
If we know that |...| can never be negative, we can directly deduce that this equation does not have any solution.
6.6. 2.2*3= 6.6
i hope this makes since
