Answer: -69q+74
Step by step:
1. Use distributive property.
8⋅10+8(−6q) + 3(−7q − 2)
Multiply 8 • 10 then -6 • 8
80 - 48q + 3(-7q - 2)
2. Use distributive property again.
80 - 48q + 3(-7q - 2)
Multiply -7 • 3 then 3 • -2
80 - 48q -21q - 6
3. Simplify
Subtract 6 from 80 then subtract 21q from -48q.
-69q + 74
8(10 - 6q) + 3(-7q - 2) = -69q + 74

Step-by-step explanation:
Answer:
[μ-error, μ + error]
[14000- 3000, 14000 + 3000]
Step-by-step explanation:
We write it how an interval, where the center of the interval is the mean, thus
[μ-error, μ + error]
First we calculate the mean
μ = (11000+17000)/2
μ = $14000
And the error is the absolute value of the difference between the mean an either extreme values
error = |14000 -17000| = |14000 - 11000| = 3000
Then
[14000- 3000, 14000 + 3000]
Answer:
![\sqrt[3]{17}= 2.57128=257128](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B17%7D%3D%202.57128%3D257128)
×
Step-by-step explanation:
We need to find: ![\sqrt[3]{17}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B17%7D)
in decimals. To do this, we are going to need the help of a calculator. After plugging the values, we get that:
![\sqrt[3]{17}= 2.57128 = 257128](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B17%7D%3D%202.57128%20%3D%20257128)

In this case, I just considered 5 significant figures!
