Step-by-step explanation:
a = 2
b = 1
c = 4
<h2>Question:</h2>

= Solution ,
= 3 × 2 × 4 - 2 + 2 × 1
= 24 - 2 + 2
= 24 + 2 - 2
= 26 - 2
= 24
hence the answer is 24....

other subset (0, infinity)
Answer:
<em>4.52secs</em>
Step-by-step explanation:
Given the height of a falling object expressed as;
d=3t+5t^2
If the object travel 84 feet, we are to find the time t it takes to travel. On substituting;
84 = 3t+5t^2
3t+5t^2 - 84 = 0
t = -5±√25-4(3)(-84)/2(3)
t = -5±√25+1008/6
t = -5±32.14/6
t = -5+32.14/6
t = 27.14/6
<em>t = 4.52 secs</em>
<em>Hence it will take 4.52secs for the object to travel 84feet</em>
Answer:

Step-by-step explanation:
We need to find which statements are true.
Solution to find the same we will solve each statement and will conclude the same.
1. 
Now On solving we get;


So we can see that 0.70 > 0.66
Hence The given statement is False.
2. 
Now On solving we get;


So we can see that 0.5625 > 0.5
Hence The given statement is True.
3. 
Now On solving we get;


So we can see that 1.33 > 1.2
Hence The given statement is False.
4. 
Now On solving we get;


So we can see that 0.82 > 0.66
Hence The given statement is False.
