Answer:
5x-2
Step-by-step explanation:
15x^2-x-2
15x^2+5x-6x-2
factorize
5x(3x+1)-2(3x+1)
Sol: (3x+1)*(5x-2)
Option A:

Solution:
ABCD and EGFH are two trapezoids.
To determine the correct way to tell the two trapezoids are similar.
Option A: 
AB = GF (side)
BC = FH (side)
CD = HE (side)
DA = EG (side)
So,
is the correct way to complete the statement.
Option B: 
In the given image length of AB ≠ EG.
So,
is the not the correct way to complete the statement.
Option C:
In the given image length of AB ≠ FH.
So,
is the not the correct way to complete the statement.
Option D:
In the given image length of AB ≠ HE.
So,
is the not the correct way to complete the statement.
Hence,
is the correct way to complete the statement.
