To solve for n you have to get n on one side of the equation by itself.
n-6m=8
take -6m and add to both sides. so the side that has n evens out to 0. then you have
n=6m+8
it is this way because you can only add like terms. This should be all you need to do.
Hope this helps
Answer: negative, positive, zero, and undefined.
Step-by-step explanation: as x increases. The slope of a line can also be interpreted as the “average rate of change”.
Since x is the length, then x+7 has to be the width.
The area of a rectangle can be found via the formula :
A = length * width
So if we replace the area with the given number (170) and the length, and width, with what we assumed, we get..
170 = x * (x+7)
[which is.. ]
170 = x^2 +7x
0 = x^2 +7x - 170
And that is the answer.
