put a positive factor back into the square root:

solve for x
(2x-a)/b=(ax+1)/c, if ab ≠ 2c

Part 1)

Part 2)

Step-by-step explanation:

Part 1) we know that

To put factor back into the square root, we have to put squared value

we have

Remember that

substitute in the expression above

Part 2) we have

Solve for x

That means----> Isolate the variable x

Multiply in cross

Apply distributive property

Group terms

Factor x left side

Divide by (2c-ab) both sides

6: 07 is your answer

step-by-step explanation:

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.
