Answer:
Step-by-step explanation:
This can only be written one way.
Let the number = x
x^2 - 10
is how the statement translates.
x^2 = x*x
the 2 means that you need two xs.
The ^ means that you multiply the two xs.
Answer:

Step-by-step explanation:
Simplify using ![a\frac{n}{m} =\sqrt[m]{a^n} :\sqrt{6^3}](https://tex.z-dn.net/?f=a%5Cfrac%7Bn%7D%7Bm%7D%20%3D%5Csqrt%5Bm%5D%7Ba%5En%7D%20%3A%5Csqrt%7B6%5E3%7D)
Factor and rewrite the radicand in exponential form: 
Rewrite the expression using ![\sqrt[n]{ab} =\sqrt[n]{a}*\sqrt[n]{b} : \sqrt{6^2x\sqrt{6}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bab%7D%20%3D%5Csqrt%5Bn%5D%7Ba%7D%2A%5Csqrt%5Bn%5D%7Bb%7D%20%3A%20%5Csqrt%7B6%5E2x%5Csqrt%7B6%7D)
Simplify the radical expression

substitute every x in the equation with (-2)
f(-2)=3*2*(-2) = -12
dunno if I get your equation correctly, pls check how you have written it
This is false. However all squares are parrallelograms.
We first need to find the difference between $70 and $49.
$70 - $49 = 21
Now we find out what percent $21 is of $70.
21/70 × 100 = 30%.
That means the discount is 30%!
Now we must find 30% of $100, which is $30.
Then we subtract $30 from $100.
$100 - $30 = 70$
