Answer:
The value of x is 2/3.
Step-by-step explanation:
The perimeter of a square is 4s.
Substitute the value and simplify.
4( 3x - 2 ) Distribute
12x - 8 In this case this is an equation
12x - 8 = 0 Add 8 on both sides
12x = 8 Isolate the variable by dividing 12 on both sides
x= 2/3
You must isolate the variable in order to solve equations with variables.
Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <em><u>ONLY </u></em>one side of the equation.

Answer:
The minimum IQ score will be "126".
Step-by-step explanation:
The given values are:
Mean
![\mu = 100](https://tex.z-dn.net/?f=%5Cmu%20%3D%20100)
Standard deviation
![\sigma=15](https://tex.z-dn.net/?f=%5Csigma%3D15)
Now,
⇒ ![P(z>x)=4 \ percent \ i.e., 0.04](https://tex.z-dn.net/?f=P%28z%3Ex%29%3D4%20%5C%20percent%20%5C%20i.e.%2C%200.04)
⇒ ![P(z>\frac{x- \mu}{\sigma} )=0.04](https://tex.z-dn.net/?f=P%28z%3E%5Cfrac%7Bx-%20%5Cmu%7D%7B%5Csigma%7D%20%29%3D0.04)
⇒ ![1-P(z \leq \frac{x-100}{15})=0.04](https://tex.z-dn.net/?f=1-P%28z%20%5Cleq%20%5Cfrac%7Bx-100%7D%7B15%7D%29%3D0.04)
⇒ ![\frac{x-100}{15}=z0.96](https://tex.z-dn.net/?f=%5Cfrac%7Bx-100%7D%7B15%7D%3Dz0.96)
![=NORMDIS(z=0.96)](https://tex.z-dn.net/?f=%3DNORMDIS%28z%3D0.96%29)
![=1.751](https://tex.z-dn.net/?f=%3D1.751)
⇒ ![x=100+15\times 1.751](https://tex.z-dn.net/?f=x%3D100%2B15%5Ctimes%201.751)
![=126.265 \ i.e., 126](https://tex.z-dn.net/?f=%3D126.265%20%5C%20i.e.%2C%20126)
