The answer is 6x-12
Hope this helps!
Hello from MrBillDoesMath!
Answer:
The first choice (with the square roots of negative integers)
Discussion:
Number such as 0,1,2,3 or -4, -5, -8, or Pi, sqrt(12), sqrt(15), or 1/2, 1/10, 1/14 are all REAL numbers.
The square root of a negative number, such as sqrt(-3), is an imaginary number. The answer is the first choice
Thank you,

Answer:
The temperatures were more consistent in Springville
Step-by-step explanation:
This question is on consistency of data
Generally, consistency of a data set is measured by determining the range, the variance or the standard deviation.In this case, we will use the standard deviation.
A small standard deviation means higher consistence.A lower standard deviation will mean easy to predict a value because most of the values are closer to the average value.When the variations are less, a better analysis can be performed on a set of data.
Temperatures were more consistent in Springville that had a standard variation of 4F compared to Dakota that had a standard deviation of 6.8F
Answer:
½pi or 0.5pi units²
Step-by-step explanation:
Area : angle
9pi : 2pi
x : pi/9
9pi/2pi = x/(pi/9)
4.5 × pi/9 = x
x = ½pi or 0.5pi units²
Answer:
12a+2b
Step-by-step explanation:
1. Expand by distributing terms.
20a-8b-2(4a-5b)20a−8b−2(4a−5b)
2. Expand by distributing terms.
20a-8b-(8a-10b)20a−8b−(8a−10b)
3. Remove parentheses.
20a-8b-8a+10b20a−8b−8a+10b
4.Collect like terms.
(20a-8a)+(-8b+10b)(20a−8a)+(−8b+10b)
5. Simplify.
12a+2b12a+2b
6.Answer
12a+2b
