3n-5=-8(6+5n) SOLVE

Answers

Answer 1

Answer: It's gonna be a long problem: Remember PEMDAS
3n-5=8(6+5n)
3n-5= 48 + 40n Distribute 8 into parenthesis
3n-3n-5=48+40n-3n Put variable on one side.
-5-48=48-48+37n Isolate the variable
-43/37=37n/37 Isolate variable more
-1.162=n Simplify
The answer is repeating; that is a shortened version.

Answer 2

Answer:

t's gonna be a long problem: Remember PEMDAS

3n-5=8(6+5n)

3n-5= 48 + 40n Distribute 8 into parenthesis

3n-3n-5=48+40n-3n Put variable on one side.

-5-48=48-48+37n Isolate the variable

-43/37=37n/37 Isolate variable more

-1.162=n Simplify

The answer is repeating; that is a shortened version.

What is the product of 6x – y and 2x – y + 2?A=8x2 – 4xy + 12x + y2 – 2y
B=12x2 – 8xy + 12x + y2 – 2y
C=8x2 + 4xy + 4x + y2 – 2y
D=12x2 + 8xy + 4x + y2 + 2y

Answers

Answer:

Option (B) is correct.

The product of 6x – y and 2x – y + 2 is $12x^2-8xy+12x+y^2-2y$

Step-by-step explanation:

Consider the given expressions 6x – y and 2x – y + 2

We have to find the product of the above two given expressions,

$(6x-y)(2x-y+2)$

multiply first term of first expression by each term of second expression and similarly second term of first expression by each term of second expression

$\Rightarrow 6x(2x-y+2)-y(2x-y+2)$

On solving, we get,

$\Rightarrow 12x^2-6xy+12x-2xy+y^2-2y$

Solving further by combining like term, we get,

$\Rightarrow 12x^2-8xy+12x+y^2-2y$

Thus, The product of 6x – y and 2x – y + 2 is $12x^2-8xy+12x+y^2-2y$

Hence, option (B) is correct.

What is the value os f(150), And what does f(150) represent?

Answers

f(150) = 3×150 + 20 = 470

Final answer:

f(150) refers to a function f applied to the input 150. Without information about the form of function 'f', we can't tell the specific value of f(150). The value of f(150) symbolizes the outcome after applying the function 'f' to 150.

Explanation:

The question is asking about f(150) which relates to the concept of function in Mathematics. In a function f(x), the input is represented by 'x', and the output, which is the result of applying the function to 'x', is represented by f(x). Therefore, f(150) means that the function f is being applied to the number 150. Without any specific information about the function 'f', we cannot determine the exact value of f(150). The value of f(150) represents the outcome resulted by applying the function 'f' to the input 150.
