Answer:
4/9
Step-by-step explanation:
We know that the opposite is the additive inverse.
For example, 8+(−8)=0 where 0 is the identity for addition.
Given that we have to compute the sum of 5x+20 and the opposite.
Given
5x+20
opposite of 5x+20 = -(5x+20)
so
The sum of 5x+20 and the opposite:
5x+20 + -(5x+20)
Distribute the Negative Sign
Combine Like Terms
Therefore, the sum of 5x+20 and the opposite is: 0
Thus, the equivalent expression is:
4-7x= 39
Subtract 4 from both sides
-7x= 35
Divide both sides by -7
x= -5
The value of x+1= (-5)+1= -4.
If u ask to √27 is en even number so of course it's gonna be 5.19615242270663 so ÷that by 49 is 0.10604392699401
V= pi r^2h
180= pi (5)^2h
180=78.5h
Divide by 78.5
h= 2.29
h= 2.3
Sorry could not type pi symbol
