<h3>Answer:</h3>
A. 3x² +6
<h3>Explanation:</h3>
(f-g)(x) = f(x) -g(x) = (4x²+1) -(x²-5) . . . . . substitute the function definitions
... = 4x² +1 -x² +5 . . . . . . . . . . . eliminate parentheses
... = (4-1)x² +(1+5) . . . . . . . . . . . collect like terms
... = 3x² +6
The answer is...
three and seventy five hundredths
This written out is:
2/5 + 4/3
------------
3/5
Roughly, now first we need to change the denominators to all match up in order to properly solve this problem.
Both 5 and 3 go into 15, 5 goes into 15 3 times and 3 goes into 15 5 times. With that said, multiply the individual numerators by 5 and 3.
2/5 -> 2*3/15 -> 6/15
4/3 -> 4*5/15 -> 20/15
3/5 -> 3*3/15 -> 9/15
With this, we then add the top numerator of the overall problem:
26/15
------- | With this we now cross-multiply.
9/15
26/15 * 15/9 = 390/135 | Now to simplify this.
135 goes into 390 twice, as 270. Subtract 390 by 270, leaving us with 120.
Meaning: 2 120/135 is the answer, but now to simplify. Divide 120 and 135 by 5 to lessen this.
24/27 | Divide this by 3 to get your most simplified answer.
8/9 | Leaving us with the answer of:
2 8/9
I hope this helps, have a great rest of your day! ^ ^

Answer:
He raised $25.50 over his fund raising goal
Step-by-step explanation:
Here, we want to calculate his fund raising goal.
Let his fund raising goal be $x
We are told that he raised 151% of his fundraising goal;
Thus,
mathematically;
151% of x = 75.5
151/100 * x = 75.5
151x = 100 * 75.5
151x = 7550
x = 7550/151
x = $50
So the amount he raised over his fund raising goal will be $75.50 - $50 = $25.50
Answer:
or 
rounded to the nearest tenth
Step-by-step explanation:
1. Find the area of the base and the top, which are circles.
Area of circle : 
= 986.960440109
There are 2 circles, soooooo....= 986.960440109 x 2 = 1973.92088022
2. Find the rest of the area of the cylander.
So, we have to find the circumference of the circle.
Circumference :2
10 = 62.83
3. Multiply circumference by height.
62.83 x 7 = 439.81
4. Add all of the products.
439.81 + 1973.92088022 = or rounded to the nearest tenth
