Answer:
11x-10
Step-by-step explanation:
1.Rearrange terms
-2(4-3x)+(5x-2)
-2(-3x+4)+(5x-2)
2.Distribute
-2(3x+4)+(5x-2)
6x-8+(5x-2)
3.Eleminate redundant parentheses
6x-8+(5x-2)
6x-8+5x-2
4.subtract the numbers
6x-8+5x-2
6x-10+5x
5.Combine like terms
6x-10+5x
11x-10
•solution
11x-10

Answer:
700 teens
Step-by-step explanation:
If five out of 7 teens do homework every night
There are 980 teens
How many out of 980 teens would do homework every night?
Firstly divide 980 teens by 7
Which is 980/7=140
Next is,
Out of 7 teens, there are 5 who do homework every night
So, multiply 140 by 5
140×5=700 teens
This means, the reasonable prediction of teens who do homework every night out of 980 is 700 teens

Although I am not clear as to whether the radius is r—1 or otherwise, but if i work with the values i see then:
Volume — T. S. A.
= πr²h — (2πr²+2πrh)
So after the simplification, I substitute the values given,
r= r—1 and h=h—1
And the answer is...
π(r—1)(rh—3r—3h+5)!
