S(x)=3x²
t(x)=4x
(t*s)(-2)=(3x² * 4x)(-2)=(12x³)(-2)=-24x³
Answer: (t*s)(-2)=-24x³
Answer:
D. 
Step-by-step explanation:
Determine the groups: 
- 
Factor out terms:
The -2 was factored out in the second group to ensure that both groups had
(x-12).
Answer:
(3x+5y)/8
Step-by-step explanation:
The total amount is 150+250=400
We then do (3x+5y)/2 × 1/400
This equals (3x+5y)/800
We multiply that by 100 giving us the final answer.
Answer:
1/6
Step-by-step explanation:
Total number of outcome = 6. This is because it has 6 sides from number 1 to 6.
A) Probability of getting number 3 = 1/6 . This is because we have only one 3 in the outcome.
B) probability of getting odd number = total number of odd number ÷ total outcome .
The odd number are 1,3,5.
Therefore prob(odd) = 3/6 =1/2
