Answer by JKismyhusbandbae: 6n-16
Arithmetic Formula: 
Use the following formula to determine any number in an arithmetic sequence:
an = a1 + d (n – 1)
a1 = the first term.
d = common difference
n = term number
Answer:
⅔πx³
Step-by-step explanation:
The formula for the volume of a cone is
V = ⅓πr²h
Let x = radius of base.
Then 2x = height, and
V = ⅓πx²·2x = ⅔πx³
The answer is -4/7
First, you distribute the -3 and -5 through the parentheses.
-6x+6-15x-15=3
Then combine like terms
-21x-9=3
Do opposite operation
9+3=12
That leaves
-21x=12
Divide both side by -21
X= -4/7
Answer:
Two points are collinear when they lie on the same line. Points are collinear but not lines. Rather when two lines lie on the same plane we say they are coplanar.
Hence, line AB and CD are NOT collinear, so they are noncollinear and they are coplanar.
Two or more lines are said to be intersecting, when the lines meet at some point, when lines are not intersecting they are said to be parallel.
Recall that one of the properties of a rectangle is that opposite sides are parallel.
Notice that line AB and CB are the opposite sides of the rectangle ABCD.
Thus, line AB and CD are not intersecting but are parallel.
Therefore, the terms that best describe lines AB and CD are
parallel
noncollinear
coplanar
