<h3>Answer:</h3>

2.25

<h3>Explanation:</h3>

Consider the square ...

... (x+a)² = x² +2ax +a²

The constant term (a²) is the square of half the x-coefficient: a² = (2a/2)².

The x-coefficient in your expression is 3. The square of half that is ...

... (3/2)² = 9/4 = 2.25

Adding 2.25 to both sides gives ...

... x² +3x + 2.25 = 6 + 2.25

... (x +1.5)² = 8.25 . . . . completed square

Converting units is always an exercise in linear relationships. how many inches is 2.50 m? (2.54 cm=1.0 inch)

madam [21]

There are 98.4252 inches in 2.50m.

Unit Conversion is defined as a process that involves multiplication and division by a numerical factor or a particular conversion factor.

For Example .Convert 2m into cm.

As we know that 1m=100cm

multiplying both sides by 2 we get

2m = 200 cm.

According to the question

It is given that 2.54 cm = 1 inch

$1cm = \frac{1}{2.54} inch$

$100cm=\frac{100}{254} inch$

$1m = \frac{100}{2.54}$ ( as 100cm = 1m)

we need 2.50 m So we multiply both sides by 2.50

$2.50m=\frac{2.50*100}{2.54} \\\\ 2.50m=\frac{250}{2.54}$

$2.50m=98.4252 inch$

Therefore , there are 98.4252 inches in 2.50m.
