A is the coefficient of x in this case.
So A. is the right answer as you need to divide by the coefficient.
Answer:
27x^3 - 54x^2 + 36x - 8
Step-by-step explanation:
(3x - 2)^3
= (3x - 2) (3x - 2) (3x - 2)
= 27x^3 - 54x^2 + 36x - 8
Hope this helps :)

Answer:
x=47, y=68
Step-by-step explanation:
Add the two equations. Then we get
-y=-68
y=68
Substituting the value of y in the first equation,
8x-6(68)=-32
8x-408=-32
8x=376
x=47
Answer:
f = 26
d=112
e=42
Step-by-step explanation:
as far as what i can see, the first given angle is 112 and the second angle is 42.
These two angles are the angles on one straightline, therefore the missing angle will be 180 - 112 - 42 = 26 (Supplementary angle). This angle is not required and it is the missing angle on the left hand side. However, this angle should be equal to that of f (Opposite angle).
By the same way, d and e are the two opposite angles for 112 and 42, respectively.
Answer:
Step-by-step explanation:
Given:
To write: the given expression using summation notation
Solution:
Summation notation helps to write a long sum as a single expression.
In the summation notation, the variable is called the index of summation.
Let denote a set of n numbers.
Then in summation notation,
