Answer:
2d
Step-by-step explanation:
Im guessing 2 is also being added. Well basically you add 8 2 and negative 10, which gives you zero, and the value that is left from that is 2d, so its 2d
Two ratioa that are equivalent to 9/12 are
3/4
18/24
Assuming that this is just on a 2-D coordinate plane, we must convert the expressions on to a 3-D plane since translation cannot be done on a 2-D plane. This is done by adding a dummy coordinate that does not change. Let us use "1" for this case.
Matrix:
| 0 0 -2 |(x) = (x - 2)
<span>| 0 0 4 |(y) = (y + 4)
</span><span>| 0 0 1 |(1) = 1</span>
Answer:
SA = 2400 cm²
Step-by-step explanation:
SA of a cube = S² x 6 (the number of its faces)
SA = 20² x 6
SA = 400 x 6
SA = 2400 cm²
It should be D, I did the math :)
