Answer:
heya! ^^
so the question demands us to calculate what is 20% of 60.
that's quite simple. so let's see how we gótta do this question.
![\\\\ \fbox{20\% \: \: of \: \: 60} \\ \\ \dashrightarrow \: \frac{2\cancel0}{\cancel{100}} \times 6\cancel0 \\ \\ \dashrightarrow \: 2 \times 6 \\ \\ \dashrightarrow \: 12](https://tex.z-dn.net/?f=%5C%5C%5C%5C%20%5Cfbox%7B20%5C%25%20%5C%3A%20%20%5C%3A%20of%20%5C%3A%20%5C%3A%20%2060%7D%20%5C%5C%20%20%5C%5C%20%20%5Cdashrightarrow%20%5C%3A%20%20%5Cfrac%7B2%5Ccancel0%7D%7B%5Ccancel%7B100%7D%7D%20%5Ctimes%206%5Ccancel0%20%20%5C%5C%20%20%5C%5C%20%5Cdashrightarrow%20%5C%3A%202%20%5Ctimes%206%20%5C%5C%20%20%5C%5C%20%5Cdashrightarrow%20%5C%3A%2012)
hope helpful :D
Answer:
x=6 and x=-8
To solve this, you would treat x-6=0 as one equation, you add 6 to each side to get rid of -6, hence you would get x=6.
Same goes for x+8=0, subtract 8 from each side to get rid of the +8, then you get x=-8
Answer:
![2a^{\frac{5}{2}}-4a^{-\frac{1}{2}}](https://tex.z-dn.net/?f=2a%5E%7B%5Cfrac%7B5%7D%7B2%7D%7D-4a%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D)
Step-by-step explanation:
It looks like you want to expand the expression ...
![\sqrt{a}\left(2a^2 -\dfrac{4}{a}\right)](https://tex.z-dn.net/?f=%5Csqrt%7Ba%7D%5Cleft%282a%5E2%20-%5Cdfrac%7B4%7D%7Ba%7D%5Cright%29)
Use the distributive property and rules of exponents.
![=2a^{(\frac{1}{2}+2)}-4a^{(\frac{1}{2}-1)}\\\\=\boxed{2a^{\frac{5}{2}}-4a^{-\frac{1}{2}}}](https://tex.z-dn.net/?f=%3D2a%5E%7B%28%5Cfrac%7B1%7D%7B2%7D%2B2%29%7D-4a%5E%7B%28%5Cfrac%7B1%7D%7B2%7D-1%29%7D%5C%5C%5C%5C%3D%5Cboxed%7B2a%5E%7B%5Cfrac%7B5%7D%7B2%7D%7D-4a%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D%7D)
_____
The relevant rules of exponents are ...
√a = a^(1/2)
1/a = a^-1
(a^b)(a^c) = a^(b+c)
Answer:
i think its 6............
The answer is 144 iPhones. To get this answer, you first find the volume of the crate which is 10368’’. Then, you find the volume of the iPhones, which is 72’’. Finally, you divide 10368 by 72 to find how many iPhone are in each crate, and there are 144.
