Calculate the volume of a cylinder using the formula V = r2 × π × h. Begin by first finding the area of the circle at one end. Square the radius of the circle and multiply the result by "pi" (the symbol π), or approximately 3.14. Multiply this result by the cylinder's height to get its volume.
The equivalent expression of -(-5q-3.1r+4.5) without parenthesis is 5q + 3.1r - 4.5
In order to get the equivalent expression without parenthesis, we will use the distributive law. Also, we must know that:
- - × - =+
- + × - = -
- + × + =+
Given the expression -(-5q-3.1r+4.5)
This can also be written as -1 (-5q-3.1r+4.5)
On expansion
-1 (-5q-3.1r+4.5)
= -1(-5q) -1(-3.1t) -1(+4.5)
Using the sign rule, the result becomes:
= 5q + 3.1r - 4.5
Hence the equivalent expression without parenthesis is 5q + 3.1r - 4.5

There is no solution to the problem (x)=x+3!
Sorry, Love~ :(
I think it's 1 3/4. I had one similar earlier.
