Hello!
Here are the steps to find your answer:
8(4 - x) = 7x + 2
32 - 8x = 7x + 2
32 - 2 = 7x + 8x
30 = 15x
2 = x
x = 2
I hope this helps you! Have a lovely day!

Thousand is 1,000, or 10^3, when multiplied by the 100 in 427, it becomes 10^5. Because we divided 427 and put the notation in the 10^#. It would be 4.27, once we add the ten^#, it becomes..
Answer: 4.27*10^5
Answer:

Step-by-step explanation:
To factor the expression
you need to know its roots.
First find the discriminant of this quadratic polynomial:

Then the roots of the expression
are

Now the factored form is

Answer: 4^9
Step-by-step explanation:
4^-7 is just 1/4^7 so this is equal to 4^2 divided by 1/4^7. Dividing by a fraction is the same thing as multiplying by its reciprocal (just flip the fraction). So this whole equation is equal to 4^2 multiplied by 4^7. And when you multiply two exponents with the same base, the exponents are just added. So, your answer should be 4^9. Hope this helps! :)
Your answer is 51 because you have to trade the 3 and the 5 out with the z and the x so to find your answer you add -8+9+5 then you *3 bc z=3 then you add 7 * 5 so you answer is 51
