Hi there! The answer is 9 square units
To find the area of a triangle we use the following formula:
Area = 0.5 * base * height.
The base of this triangle:
AC = 6
The height of this triangle:
BD = 3
Filling in this formula gives us:
Area = 0.5 * 3 * 6 = 9
Therefore, the answer is 9 square units

Answer:
28 -16n
Step-by-step explanation:
Use the distributive property, then collect terms.
4 +8(-2n +3)
= 4 +8(-2n) +8(3)
= 4 -16n +24
= 28 -16n
_____
This could also be written
-16n +28
but then the leading sign would be negative. Sometimes leading minus signs get lost, so I prefer the first term to be positive.
