In triangle abc ad/db = ce/eb. complete the proof showing the segment de is parallel to segment ac.
1.
a) (ad/db) + 1 = (ce/eb) + 1
b) (ad/db) + de = (ce/eb) + de
c) ad * eb = ce * db
2.
a) corresponding sides of congruent triangles are congruent.
b) addition property of equality
c) cross multiplication
edit: answer is 1.a and 2.b (verified correct) to

1.

2. Addition property of equality

Step-by-step explanation:

In triangle ABC,

The addition property of equality states that if the same amount is added to both sides of an equation, then the equality is still true.

Use addition property of equality, add 1 to both sides of previouse equality:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
