Distributive property lets you distribute 3(3+x)
so this is the property, note: xy=x times y=x(y)
a(b+c)=(ab)+(ac)
it does not let me install the page i am so sorry I would help you but this thing is to old sorry again :(

Step-by-step explanation:
Answer:
r = +8 or -8
Step-by-step explanation:
This is because when you square -8 or +8, you will get 64
Let x represent the width of the rectangle.
We know 2x=length
Perimeter of a rectangle is 2(length)+2(width)
So we can make an equation for the perimeter of this particular rectangle.
2(2x)+2(x)=60
4x+2x=60
6x=60
x=10.
Since the width is equal to x, we know that the width of this rectangle is 10 m.
And, the length is twice of the width.
10*2=20
Therefore, the length of the rectangle is 20 meters.
