Step-by-step explanation:
Number of choices = 5C2 = 5 * 4 / (1 * 2) = 10.
Answer:
30
Step-by-step explanation:
pythagoras theorem dictates:
a squared plus b squared=c squared
576+324=900
take the square root of that
30
It would be C. Because PEMDAS. Division goes first in this equation. So it’d be 15 divided by 3 plus 6
-4(9)(-5) = (-36)(-5) because -4(9) = -36. (-36)(-5) = 180
