The answer is the last option: The associative property of multiplication
3 (x + 1) = 5 + x
First you must distribute the 3 to the values inside the parentheses:
3 (x + 1) = 5 + x
(3 * x) + (3 * 1) = 5 + x
3x + 3 = 5 + x
Now you must combine like terms. Like terms are numbers that have matching variables like 3x and x OR are numbers with out variables like 3 and 5.
3x - x = 5 - 3
2x = 2
Next, to completely isolate x, divide 2 to both sides. Since 2 is being multiplied by x, division (the opposite of multiplication) will cancel 2 out (in this case it will make 2 one) from the left side and bring it over to the right side.
2x / 2 = 2 / 2
1x = 1
Check:
3 (1 + 1) = 5 + 1
3 (2) = 5 + 1
6 = 6
^^^This is true, therefore:
x = 1

6:50 is the answer! Hope this helps. You can figure this out by crossing out the ones you KNOW are factors of 4 and 20. And 6:50 is NOT a factor of them . Hope this helped!!
We know that:
perimeter = (2 x width) + (2 x length)
Plugging in what we know to this equation:
40 = (2 x 8) + (2 x length)
40 = 16 <span>+ (2 x length)
</span>24 = <span>2 x length
</span>12 = length
The length of the room is 12 feet
I would say that d is not equivalent to that equation
