<span>The width is 6 inches and the length is 26 inches.
Explanation:
L=4w+2, since the length is 2 more than 4 times the width.
The perimeter is given by P=2L+2w; using our equation for L, we have
P=2(4w+2)+2w.
Using the distributive property, we have
P=2*4w+2*2+2w
P=8w+4+2w.
Combining like terms, we have P=10w+4.
We know the perimeter is 64, so we have
64=10w+4.
Subtract 4 from both sides:
64-4=10w+4-4
60=10w.
Divide both sides by 10:
60/10 = 10w/10
6=w.
Substitute this into the equation for length: L=4*6+2=24+2=26</span>

Step-by-step explanation:
So we know that a gym membership costs $25 plus $14 each month.
In other words, the one-time cost is $25 and there will be a cost of $14 each month.
We can write this as:

Where f(x) equals the total cost given the number of months x.
For 6 months, the total cost will be:

Answer:

Step-by-step explanation:
As with any "solve for ..." problem, you undo what is done to the variable of interest. Here, what is done is ...
- A is added
- the sum is multiplied by Y
You "undo" these operations in reverse order (from the bottom of the list up). To undo multiplication, you multiply by the reciprocal:

To undo the addition of A, add the opposite of A:
