Answer:

<h2>12 inches</h2>

Step-by-step explanation:

Given, 

Measure of a two-story building (in feet)

= 21 feet

So, Measure of the building in (in inches)

= 3 inches

Therefore, 

By the problem, 

21 feet building

= 3 inches

So,

1 feet building

$= \frac{3}{21} inches$

Then,

84 feet building

$= \frac{3}{21} \times 84 \: inches$

= 3 × 4 inches

= 12 inches

<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
