Answer:
an expression is numbers, symbols and operators (such as + and ×) grouped together that show the value of something and a equation is an equation says that two things are equal. (7+2=9) this is an equation
Answer:
Table C
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
Find the value of the constant of proportionality in each table
Table A
For 
------>
For 
------>
This table has different values of k
therefore
the table A does not represent a proportional relationship
Table B
For ------>
For 
------>
For 
------>
This table has different values of k
therefore
the table B does not represent a proportional relationship
Table C
For ------>
For ------>
For 
------>
For 
------>
This table has the same value of k
therefore
the table C represent a proportional relationship
Table D
For ------>
For ------>
For ------>
For 
------>
This table has different values of k
therefore
the table D does not represent a proportional relationship
Answer:
Equilateral Triangle
Side a = 1
Side b = 1
