The table contains the proof of the theorem of the relationship between slopes of parallel lines. What is the missing statement for step 6

1. ABC and DEF are similar.

2. Property of Similar Triangles

3. Property of Proportion

4. slope of = definition of slope

5. slope of = definition of slope

6. Substitution Property of Equality

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
