Answer:
Option 2 is correct.
Step-by-step explanation:
Given the coordinates of lines segment (3, 10) and (7, 8). we have to find the mid-point of given line segment.
Mid-point formula states that if
and
are the coordinates of end points of line segment then the coordinates of mid-point are

∴ Coordinates of mid-point of line segment joining the points (3, 10) and (7, 8) are

Hence, option 2 is correct.
For this case we must find the product of 
By definition, the distributive property states that:

Then, according to the expression we have:

Answer:

Option C
The answers are 5:30 6:20 8:120
Answer:
Refer to the chart below for help:
SSS: When all three sides are equal to each other on both triangles, the triangle is congruent
AAS: If two angles and a non-included (you can think of it as outside) side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
ASA: If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
SAS: If any two angles and the included side are the same in both triangles, then the triangles are congruent.
