Answer:
Ravi had 355ml water to begin with.
Step-by-step explanation:
Given that,
amount of water that Gwent pour in Ravi = 256 ml
amount of water that Henry pour in Ravi = 189 ml
amount of water after each have poured = 800 ml
suppose amount of water ravi had before both poured water in it = x
Equation
256 + 189 + x = 800
445 + x = 800
x = 355ml
Initially ravi had 335ml of water.
You can use the distributive property of multiplication over addition to find the equivalent expression to the given expression.
The expression which is equivalent to the given expression is given by
Option D: 
<h3>What are equivalent expressions?</h3>
Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
<h3>What is distributive property of multiplication over addition?</h3>
Suppose a, b and c are three numbers. Then we have:

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
<h3>Using the above property and the fact that 28 and 35 are multiples of 7 to get the equivalent expression</h3>
The given expression is 
Since 28 = 7 times 4 and 35 = 7 times 5
Thus,

Thus,
The expression which is equivalent to the given expression is given by

For the cut glass pieces to be rectangular in shape, the glass cutter should ensure:
- All four interior angles = 90° each.
- Opposite sides are parallel and equal to each other.
- Diagonals should be of the same length and should bisect each other.
<h3>Properties of a Rectangle</h3>
- All four angles of a rectangle are 90° each.
- There are two pairs of parallel sides that are equal in length.
- The diagonals bisect each other and are of equal length.
Thus, to ensure the cut glass pieces are rectangular in shape, he should ensure the following:
- Make the four interior angles 90° each.
- The opposite sides should be parallel and equal to each other.
- The diagonals should be of the same length and should bisect each other.
