It looks like you're doing good with breaking-down the composite into digestible pieces. So, don't stress too much!
Keep in mind that the area for a 3D shape is Bh, where "B" is the area of a face & "h" is the height.
#5
Shape A is 3X4X9.
First, calculate the area of a face:
9X4= 36
Multiply by height:
36X3= 108
The process is the same with shape B.
3X4X8
Calculate area of face:
8X4= 32
Multiply by height:
32X3= 96
Now you add both areas:
108+96= 204 cubic feet
I think you're doing pretty good, just don't over think things too much. Try #8 with the similar process seen here. Just comment if you get stuck.
Hope this helps!
Answer:
I believe that the answer is A
Answer:
1.2x + 3
Step-by-step explanation:
It has to have +3 because 0 alresdy starts at 3 than use any point (I choose (5,9)) and find how much changed. The point moved 6 up and 5 to the right so divide 6/5 and get 1.2. Then test it with other points. (2,5.4) is a great example because it shows that whatever the equation is it is not 1.5 or anything above.
The measure of the exterior angle is equal to the sum of the remote interior angles. Overall the sum of all the angles of a triangle is 180 degrees.
As given in the question,
Two remote interior angles measure = 
Hence, the exterior angle will be 99°
Option B is correct- The exterior angle measures 99˚.
Answer:
x = -4
Step-by-step explanation:
2(x - 4) = 6x + 8
2x - 8 = 6x + 8
-4x - 8 = 8
-4x = 16
x = -4
