Answer:

Step-by-step explanation:
Midpoint Theorem: The line joining the midpoints of two sides of the triangle is half of the length of the third side and parallel to it.
From the given figure we can see that BE is the line segment joining midpoints of two sides of the triangle. This means that
[ By midpoint theorem]
Substituting values of the lengths of BE and CD

Simplifying and solving for x.

Subtracting both sides by 2


∴ 
2^2 - 5t + 12 = 0
4 - 5t + 12 = 0
-5t + 16 = 0
-5t = -16
t = 16/5
Answer: 16/5 in fraction form or 3.2 in decimal form
The answer is c. 78 square inches.
- you take both 4 and 9, multiply them by 3 which would give you 12 and 27. then you add 27 twice and 12 twice, together and get 78.
