Answer:
The missing value is 512
![8=\sqrt[3]{512}](https://tex.z-dn.net/?f=8%3D%5Csqrt%5B3%5D%7B512%7D)
Step-by-step explanation:
Let
x ----> the missing value
we have
![8=\sqrt[3]{x}](https://tex.z-dn.net/?f=8%3D%5Csqrt%5B3%5D%7Bx%7D)
solve for x
That means-----> isolate the variable x
Elevated both sides to the cube
![8^{3}=(\sqrt[3]{x})^{3}](https://tex.z-dn.net/?f=8%5E%7B3%7D%3D%28%5Csqrt%5B3%5D%7Bx%7D%29%5E%7B3%7D)
Remember that
![(\sqrt[3]{a})^{3}=(a^{\frac{1}{3}})^3=a](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Ba%7D%29%5E%7B3%7D%3D%28a%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%29%5E3%3Da)
so
![(\sqrt[3]{x})^{3}=x](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Bx%7D%29%5E%7B3%7D%3Dx)
substitute


Rewrite

so
the equation is
![8=\sqrt[3]{512}](https://tex.z-dn.net/?f=8%3D%5Csqrt%5B3%5D%7B512%7D)

Answer:
b. $30,000
Step-by-step explanation:
According to the banker rule, the minimum annual income needed to borrowed should be maximum of 2.5% of the annual income
Given that
The amount borrowed for purchased of the home is $75,000
So based on the above information, the minimum annual income is


= $30,000
By multiplying the borrowed amount with the given percentage we can get the required minimum annual income and the same is to be shown above
Answer:
X=3
Step-by-step explanation:
Since all the sides of a square are equal, hence;
5x-2 = x+10
Collect like terms
5x-x = 10+2
4x =12
X = 12/4
X =3
Hence the value of x is 3
