Answer:
x= 5.25
Step-by-step explanation:
You have to get x alone, so do inverse operations.
(Basically, reverse what it is)
4(x-3)=9
divide 4 by both sides to get rid of 4 on left side
9/4 = 2.25
(x-3) = 2.25
Now add 3 to both sides, to get x alone
2.25 + 3 = 5.25
x=5.25
Check work
4(5.25-3) = 9
4(2.25) = 9
9=9
I think it’s B I’m not sure
Answer:
10 quarters and 12 dimes :)
Step-by-step explanation:
Answer:

Step-by-step explanation:
We are given with Second-order derivative of function f(x).

We need to find Third-order derivative of the function f(x).

We know that,
f'''(x) = (f''(x))'
So,







Therefore, 
The sides must be long enough to make a triangle. (If the sides are not long enough, they won't meet, so cannot form a triangle.)
_____
If your version of the triangle inequality includes the "or equal to" case, then the segments must be long enough to meet, even though the result may look like a line segment.
