Answer:
2 1/2 gallons
Step-by-step explanation:
add the flow plus the original number
X = 1 & Y = -1 this is the way that we should find x
It is 1000 because you multiple
Remember that the formula for the perimeter of a rectangle is:
- is the width of the rectangle
- is the length of the rectangle
Thus, in this case, you can see that we are adding two of the same monomials and two of another monomial. One monomial is and another monomial is . In this case, these monomials would fulfill the perimeter equation of a rectangle.
Applying this perimeter structure, we can find that this expression represents a perimeter equation of a rectangle with sides x + 15 and x + 5.
