they easiest way to find the right answer is to look at the 2 first terms and checking if they equal 64x³
doing so:
A:
48x³+...
B:
64x³+...
C:
9x³-48x³+...
= -39x³+...
-> the answer should be B, to make sure this is the right answer, you can just solve B
B:
(4x+3)(16x²-12x+9)
= 64x³- 48x²+36x+48x²-36x+27
= 64x³+27
-> answer B is correct
Answer:
103
Step-by-step explanation:
To estimate a value you need to add 1 to the value each time a value after the value is above 5. For example the question above
102.831853072
Let's start from 2 the last number
Less than 5 so you won't be adding one to the number before it
It becomes 102.83185307
The next number is 7 it is greater than 5 so you add 1 to the number before it. Then it becomes
102.8318531. Continue like this till you get to 8 after the decimal point.
8 is above 5 so add to 102 making 103.

Step-by-step explanation:
Answer:
The length of the first piece is 5 ft
The length of the second piece is 20 ft
The length of the third piece is 25 ft
Step-by-step explanation:
Let
x----> the length of the first piece
y ---> the length of the second piece
z ---> the length of the third piece
we know that
-----> equation A
-----> equation B
----> equation C
substitute equation B and equation C in equation A and solve for x
<em>Find the value of y</em>
<em>Find the value of z</em>
therefore
The length of the first piece is 5 ft
The length of the second piece is 20 ft
The length of the third piece is 25 ft
Given the graph, you can assume that f(x) is the y of an equation.
When f(2) is given, this means that what is the y value when x=2?
As you can see, the solution is between 8 and 10. Meaning that the closest answer is 9.
