Answer:
To subtract integers, change the sign on the integer that is to be subtracted. If both signs are positive, the answer will be positive. If both signs are negative, the answer will be negative.
2y+4=2(y+2)
2y+4=2y+4
4=4
so the answer is all real numbers or infinite solutions

Answer:
The answer is 904.778 
.
Step-by-step explanation:
-You first need the formula for the volume of a cylinder:
-Take the radius and the height of the cylinder for the formula:
-Then, you solve the formula:
So, the answer is 904.778 .
Remember, you can do anything to an equation as long as you do it to both sides
and when multiply or divide by a negative in inequalities, flip the direction of the sign
12x-39<9
add 39 to both sides
12x<48
divde bothh sides by 12
x<4
-4x+3<-6
minus 3 both sides
-4x<-9
times both sides by -1 and flip sign
4x>9
divide both sides by 4
x>9/4
