Answer:
Step-by-step explanation:
Rearrange the terms and take out a common factor of 4
4(8x^2 + 2x + 1)
I think this is as far down as you want to take it. It gives an imaginary root which you may not be familiar with.
Steps to solve:
3(5x - 8) = 6x + 39
~Distribute left side
15x - 24 = 6x + 39
~Add 24 to both sides
15x = 6x + 63
~Subtract 6x to both sides
9x = 63
~Divide 9 to both sides
x = 7
Best of Luck!
Make use of prime factorizations:
![16^5+2^{15}=(2^4)^5+2^{15}=2^{20}+2^{15}](https://tex.z-dn.net/?f=16%5E5%2B2%5E%7B15%7D%3D%282%5E4%29%5E5%2B2%5E%7B15%7D%3D2%5E%7B20%7D%2B2%5E%7B15%7D)
Both terms have a common factor of
:
![16^5+2^{15}=2^{15}\left(2^5+1\right)=2^{15}\cdot33](https://tex.z-dn.net/?f=16%5E5%2B2%5E%7B15%7D%3D2%5E%7B15%7D%5Cleft%282%5E5%2B1%5Cright%29%3D2%5E%7B15%7D%5Ccdot33)

The second one is not true! We can write
![15^7+5^{13}=(3\cdot5)^7+5^{13}=3^7\cdot5^7+5^{13}](https://tex.z-dn.net/?f=15%5E7%2B5%5E%7B13%7D%3D%283%5Ccdot5%29%5E7%2B5%5E%7B13%7D%3D3%5E7%5Ccdot5%5E7%2B5%5E%7B13%7D)
Both terms have a common factor of
:
![15^7+5^{13}=5^7\left(3^7+5^6\right)](https://tex.z-dn.net/?f=15%5E7%2B5%5E%7B13%7D%3D5%5E7%5Cleft%283%5E7%2B5%5E6%5Cright%29)
Since
, and
, we'd still have to show that
is a multiple of 6. This is impossible, because
and there is no multiple of 2 that can be factored out.
Answer:
1.6
Step-by-step explanation:
for number one, the mean would be 45 minutes
for number 9, he wants to use the number of minutes that occurred most often as that is the definition of mode
please mark branliest it’d be appreciated ♡
