Answer:
ZEXRO
Step-by-step explanation:

The process is similar to (and easier* than) adding three 4-digit numbers. Add the numbers in each column.
The sum is ...
(2+1-3)x³ +(-4+6+2)x² +(6-8-4)x +(-3+12-7)
= 0x³ +4x² -6x +2
The sum is 4x² -6x +2
_____
* The process is easier because there are no "carry" operations from one column to another as there may be when adding multi-digit numbers.
Answer: Triangle ABC is similar to triangle EDC because Measure of angle 3 equals measure of angle 4 and Measure of angle 1 equals measure of angle 5
Step-by-step explanation:
Given:
, 
Where AE and BD are the common transversals of parallel lines AB and DE,
Also, Angle CAB is labeled 1, angle ABC is labeled 2, angle ACB is labeled 3, angle DCE is labeled 4, angle CDE is labeled 6, and angle CED is labeled 5.
Thus,
( Vertically opposite angles )
( Alternative interior angle theorem)
Thus, By AA similarity postulate,

Hence, proved.
Second Option is correct.
The measure of segment PQ with P (-4.-9) and Q (4 -3) is 10 units.
<h3>How to find the length of a Line segment?</h3>
The formula for the length of the line segment is;
d = √[(x2 − x1)² + (y2 − y1)²]
We are given the coordinates of Line segment PQ as;
P (-4.-9) and Q (4 -3)
Thus, distance of line segment PQ is;
d = √[(4 − (-4))² + (-3 − (-9))²]
d = √(64 + 36)
d = √100
d = 10
Thus, we can say that the measure of segment PQ with P (-4.-9) and Q (4 -3) is 10 units.
