First thing you need to do is distributive property and that will give you
7-56-7x=-14+4x then combine like terms which will then give you
-49-7x=-14+4x Next get your letters on the left do that by subtracting 4x which will give you -49-11x=-14. After that you will add 49 to both sides which will give you
-11x= 35. Divide by -11 to get x=3.18

Answer:
Part A)

Part B)

Step-by-step explanation:
We know that the rectangle has a length of (x+5) and a width of 12 cm.
Part A)
Remember the formula for the perimeter of a rectangle:

We know that the perimeter is 86. Substitute that for P:

Substitute (x+5) for the length l and 17 for w. So:

We can simplify this to acquire our equation:

Part B)
To find the length, let's find our x first. We have the equation:

Divide both sides by 2:

Now, subtract 22 from both sides. Therefore, our x is:

To find the length, remember that the length is:

Since we now know the value of x, substitute 21 for x:

Add:

So, the length is 26 centimeters.
And we're done!
