Answer:
6 unit cubes
<u>Skills needed: Dimensioning</u>
Step-by-step explanation:
1) Layers are the length x width
The height determines the number of layers. There are 5 layers in this figure as the height is 5.
2) The length x width = 3 x 2 = 6
6 is the answer in this case.
Answer:
3(2x-y+3)
you factor every number in the math question.

Answer:
-2cos²(x) +3cos(x) -1
Step-by-step explanation:
Use the "Pythagorean identity" to replace sin²(x).
sin²(x) +cos²(x) = 1
Then ...
2sin²(x) +3cos(x) -3 = 2(1 -cos²(x)) +3cos(x) -3
= -2cos²(x) +3cos(x) -1
It should be 90 because in question it says that
1. It is extracted from the ground.
2. It took years to form.
