There are an infinite number of expressions whose value is not 18.
Here are a few of them:
4π
√7
cos(any angle)
sin(any angle)
(x + 12) whenever 'x' is NOT 6
The first one.. this is the definition of symmetry
Answer: -15
Step-by-Step Explanation:
1) Reorder the terms
36-51
2) Use the rule: a-b=-(b-a)
-(51-36)
3) Use the algorithm method
51
-36
——
15
4) After simplification, we have:
-(51-36)=-15
5)Therefore, -51+36=-15
-15
The line behind the 5 I do believe about
