Which expression is not equivalent to;

1/2 log 36 + log 30 - log 90
b b b

a. 2log 3
b

b. log 6 + log 9
b b

c. log 2
b

d. log 6
b

The expression should be equal to log 2

1/2 log 36 + log 30 - log 90

= log (36)½ + log 30 - log 90

= log 6 + log 30 - log 90

= log(6 × 30 /90)

= log 2

tube or goog would be a great resource to with that question

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
