Answer:
Non-collinear points: These points, like points X, Y, and Z in the above figure, don't all lie on the same line. Coplanar points: A group of points that lie in the same plane are coplanar. Any two or three points are always coplanar. Four or more points might or might not be coplanar.

Answer:
Step-by-step explanation:
The expression given can be rewritten as:
Because +(-n) is just -n. Then, combine like terms to get:
Substitute 
for x to get:
Which can be rewritten as:
Which is:
. as a mixed number

Answer:
49<em>r</em>
Step-by-step explanation:
Written out it would be
49 x <em>r</em> = ?
But because mathmetitians like to write quickly, we say the answer above.
Key words are the product of 49 and the length of rope. So that means we are multipling which makes 49<em>r</em> the correct expression.
6(x - 3) - 10 = 2(x + 3)
6x - 18 - 10 = 2x + 6
6x - 28 = 2x + 6
add 28 to both sides of the equation
6x = 2x + 34
subtract 2x from both sides of the equation
4x = 34
divide 4 from both sides of the equation
x = 8.5
Answer with Step-by-step explanation:
As we have given that
the product of any integer and itself is odd.
Let us take an integer = 2
When we product 2 with itself , means the square of 2 which is equal to 4
Mathematically, it is expressed as
And 4 is not an odd number as it is multiple of 2.
Hence, this contradicts the statement.
