square root of n^2, if n 0
square root of n^2, if n 0
Answer:
Square root of n^2 is -n
For example, (-3)^2 is 9, square root of nine is 3, -3=-(3)
Square root of a^2 is a,
For example, 2^2=4, square root of 4 is 2, 2=2.
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
If n < 0, the square root of n² is n
If n > 0, the square root of n² is -n.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Square root of n² when n < 0
This means,
√n² = n
Square root of n² when n > 0
This means,
√(-n)² = -n
Thus,
If n < 0, the square root of n² is n
If n > 0, the square root of n² is -n.

Cindy has a poster in the shape of a parallelogram.
What is the area of this parallelogram?
Answer:
3.60
Step-by-step explanation:
took the test
Answer:
Area of the parallelogram is 3.69 ft²
Step-by-step Explanation:
We have,
A parallelogram in shape of a poster.And we need to find the area of parallelogram.For solving,
The parallelogram is divided in 3 parts. 2 triangles and one rectangle.We will find all of there areas separately and then will add it up to have the final area of parallelogram.★Area of triangles:
= ½ × base × height
= ½ × 0.5 × 1.5
= 0.5 × 0.75
= 0.375 ft²
Since there are to triangles of same size,
= 2 × 0.375
= 0.75 ft²
★Area of rectangle:
= Length × breadth
= 1.9 × 1.5
= 2.85 ft²
★Final area of parallelogram:= Area of both triangles + area of rectangle
= 0.75 + 2.85
= 3.60 ft²

Answer:
1. C) 4 ft
2. B) 3 yds
3. C) 15840 ft
4. D) 128 oz
5. A) 105 oz
Step-by-step explanation:
For No. 1, to find how many feet, you can divide the number of inches by how many inches in a foot, or 12:
48/12 = 4 ft
For No. 2, to find how many yards, you would do the same. This time, there's 3 ft in a yard. You can also develop strategies for solving these. A ratio is a good way to visually see the problem:
3 ft 9 ft
----- = -----
1 yd ? yd
Cross multiply:
3 · ? = 9
? = 3
For No. 3, to find how many feet in 3 miles, first recall how many feet in 1 mile. That's 5280 ft.
We want 3 of those, so you would multiply it:
5280 · 3 = 5280 + 5280 + 5280
= 10560 + 5280
= 15840
For No. 4, you can use a ratio again:
16 oz ? oz
-------- = --------
1 lb 8 lb
Cross multiply:
16 (8) = ?
128 = ?
For No. 5, you can use the same ratio as No. 4:
16 oz ? oz
-------- = --------
1 lb 6.5 lb
Cross multiply:
16 (6 1/2) = ?
(16 · 6) + (16 · 1/2) = ?
96 + 8 = ?
104 = ?

{(–4, –6), (–3, –2), (1, –2), (1, 0)}
Answer:
To check if a relation is a function, given a mapping diagram of the relation, use the following criterion: If each input has only one line connected to it, then the outputs are a function of the inputs. Example: In the following mapping diagram, y is a function of x, but x is not a function of y: Line Test.
