Answer:
-5.5
4.5
Step-by-step explanation:
Given:
The numbers to order from least to greatest is given as:

In order to compare these numbers, we have to convert them in same form.
Let us simplify each number in decimal form.

So, the least number is one which has the largest value with a negative sign.
Here, -5.5 is the least number.
The next smallest number is -4.47. So, 
The next smallest number is 2. So, 
The next smallest number is 3.14. So, 
The greatest number is 4.5.
Therefore, the order from the least to greatest is:
-5.5 <
<
<
< 4.5
Answer:
1.5 units squared
Step-by-step explanation:
Area of a Triangle formula: A = 1/2bh
Pythagorean Theorem: a² + b² = c²
Since you are missing the <em>h </em>to find the area of the triangle, you must use Pythagorean to find the 3rd missing side (it is a right triangle so you can use Pythagorean).
Step 1: Use Pythagorean
2.5² = 1.5² + b²
4 = b²
b = 2
Step 2: Switch variables
b (from Pythagorean) = h (height for Area)
Step 3: Solve for Area
A = 1/2(1.5)(2)
A = 1.5
And you have your final answer.
