24 because if you put two triangles together they make a Rectangle
Step-by-step explanation:
3x+12=45
3x=45-12
3x=33
3x/3=33/3
x=11
256=2^8
256 is 2^8
I hate this " at least 20 characters to explain" may be the answer doesn't need to be explained so much
12 x 2 x 1
4 x 3 x 2
6 x 2 x 2
1 x 24 x 1
-6 x 2 x -2
- 4 x 3 x -2
- 12 x 2 x =1
=1 x 24 x -1
