2x=42-12=30
x=15
Answer:
1/3 = 0.33
Step-by-step explanation:
in a 6 sided die, there are numbers 1, 2, 3, 4, 5 and 6. So if you roll it once, there are 6 possible outcomes. so 6 is your sample space.
Out of all the possible outcomes, 5 and 6 are the only outcomes greater than 4.
P(an event occurring) = (number of ways it can occur)/(sample space)
∴p(roll greater than 4) = 2/6
=1/3
=0.333333333333333333333333............................
=0.33 (when rounded off to the 2nd decimal place)
So that's it!!! Hope i helped ya :)
Plug in 2 for x, and -4 for y
2(2)² + 3(2)(-4) - (-4)²
2² = 4(2) = 8
3(2) = 6(-4) = -24
-4² = 16
8 - 24 - 16 = answer
Simplify.
answer = 8 - 40
answer = -32
-32 is your answer
hope this helps
