<span>The perimeter of a rectangle is:
P = 2(l + w)
So we have:
P = 2(l + x)
This is one of our expressions.
It says the length is 3 times the width.
So we have 3 * x or 3x.
We can write:
l = 3x
Now plug this into the formula:
P = 2(l + x)
Plug in '3x' for 'l'</span>
In points form the answer is (-8,-4) and in equation form the answer is x=-8, y=-4 If this answered help you then please consider marking it as brainliest to help me level up to expert
