Will give 50 points!! What is the length of the line segment PQ on the coordinate grid?

A four-quadrant coordinate grid from negative 50 to positive 50 in increments of 10 is drawn. Point P is plotted on the ordered pair negative 20, 30. Point Q is plotted on the ordered pair 30, 30. The points are connected by a line.

10 units
20 units
30 units
50 units

50 units

Step-by-step explanation:

The y-coordinate of both points is 30.  Therefore, the line connecting the points is horizontal.  To calculate the length of the line segment PQ, simply subtract the x-coordinate of point P from the x-coordinate of point Q:

30 - -20 = 3 + 20 = 50

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

the equivalent expression are always the hardest ones but you look at the gcf also
