140% = 1,4 = 14/10
14/10 * x = 56 |(*10/14)
14/10 * 10/14 * x = 56 * 10/14 14/10 * 10/14 => 1
1 * x = (56*10)/14
x = 560/14

Answer: 40</span>
The answer to your answer is 10/6, flip 1/2 to 2/1 and multiply 2/1 by 5/6
Factor the problem first. So for number one, take out a seven to make it 7(x+4) and factor by subtraction of square roots on the bottom to make it (x-4)(x+4) Then, because there are factors of (x+4) on the top and bottom, cancel them out to make it 7/(x-4)
Im guessing restrictions are the values x cannot be. So you take the denominator factors of (x+4)(x-4) and set them equal to zero. x+4=0 and x-4=0.
so x cannot =4, and -4
Hope this helps you answer the next ones!
It’s A cuz it has to be square rooted
