Answer:
D, [tex]\frac{7(x-4)}{6}[/tex]
Step-by-step explanation:
Basically you have to simplify the (x² - 16). Since it is the difference of 2 squares, it's simplified as (x + 4)(x - 4). Now that everything is simplified, you can start doing the multiplication.
[tex]\frac{(x+4)(x-4)}{6x} *\frac{7x}{(x+4)}[/tex], You can cancel out the (x+4)'s
[tex]\frac{(x-4)}{6x} *{7x}[/tex], There is a common factor between 7x and 6x. The common factor is x. So cancel out both "x".
You end up with this, [tex]\frac{7(x-4)}{6}[/tex]

Answer:
12
Step-by-step explanation:
P = 8
Q = 16
The value of PQ = 16 - 8 = 8
Since M is the midpoint of PQ,
PM = MQ
PM + MQ = PQ
PM + PM = PQ
2 PM = 8
PM = 8 / 2
PM = 4
The value of M
= 8 + 4
= 12
Answer:
M = 12
Step-by-step explanation:
If you want to find the midpoint between the numbers 8 and 16, follow the simple steps below.
First, add the two numbers: 8 + 16 = 24
Secondly, divide the total by 2: 24/2 = 12
The midpoint between 8 and 16 is 12.

x ≤ 45
Step-by-step explanation:
x + 35 ≤ 80
- 35 -35
x ≤ 45
I hope this helps!
Hello!
Let's solve this inequality.
x+35≤80
Subtract 35 from both sides:
x≤80-35
x≤45
It means "less than or equal to"
So all numbers less than or equal to will make this inequality true.
Hope everything is clear.

2 + 5 is an even function.
Answers
Step-by-step explanation:
This f(x) is an even function.
Explanation:
An even function is one where f(−x)=f(x) for all x in the domain.
An odd function is one where f(−x)=−f(x) for all x in the domain.
In the case of f(x)=3x4−x2+2 we find:
f(−x)=3(−x)4−(−x)2+2=3x4−x2+2=f(x)
So f(x) is an even function.
Actually, there is a shortcut with polynomial functions:
If all of the terms have even degree then the function is even.
If all of the terms have odd degree then the function is odd.
Otherwise the function is neither odd nor even.
in our example, 3x4 has degree 4, −x2 has degree 2 and 2 has degree 0. So all of the terms are of even degree and the function is even

An absolute value inequality can be solved using a union or an intersection depending on which sign it is true or false
Answers
Answer:
True????????????????????
The statement that "An absolute value inequality can be solved using a union or an intersection depending on which sign it is" is true.
What is Absolute Value Inequality?Absolute value inequalities are kind of inequality expressions which includes the absolute value symbol in the expression.
For example : |x - 5| < 4 is an absolute value inequality.
Given statement is that,
An absolute value inequality can be solved using a union or an intersection depending on which sign it is.
If an absolute value inequality has a sign as "> 0", then the solution contains every real numbers but not values which makes the inequality 0.
in this case, union is used.
Now, if the inequality is "<" or "≤" with a positive number, the we use the intersection.
Hence the given statement is true.

The function that can be find used to find the number of circles needed to make the nth figure in the sequence is (C + 1) + 4.
How to calculate the sequence?The sequence can be illustrated through the function (C + 1) + 4 where C is the previous number. For the third picture, the number of circles will be:
= (C + 1) + 4
= 5 + 4
= 9
The fourth term will be:
