Answer:
Step-by-step explanation:
So we have the equation:
Add 2 to both sides. The left cancels:
Divide both sides by 6. The left cancels:
So, the value of x is -1.
And we're done!
Please help 6.Simplify and put in standard form: (2x5+x3−3x4−x+8)−(7 x 5+2x4−12+6x−5 x 3+x2)

We are given this:
First step is to get rid of brackets. There is no sign in front of first brackets, so we do not change the sign. In front of second brackets there is negative sign so we need to change sign for each term inside of those brackets.
Next step is to group terms with same exponent in descending order.
Now we add or substract terms with same exponent.
Standard form means ordering terms in a descending order of an exponent.

Given:
The length of field is n yards.
The length of a field in feet is a function f(n).
To find:
The function rule for this situation.
Solution:
We know that,
1 yard = 3 feet
Using this conversion, we get
n yard = 3n feet
The length of field is n yards. So, the length of the field is 3n feets.
The length of a field in feet is a function f(n). So,
Therefore, the required function rule for this situation is .
