Answer:
Option A Ordinal
Step-by-step explanation:
The most appropriate level of measurements for this category is ordinal measurements. The ordinal measurement allows for the ordering of the data but differences cannot be found for them or finding differences is completely useless using this measurements.
2.(x - 3) - 5 = 4.(x + 3) - 2x
2x - 6 - 5 = 4x + 12 - 2x
2x - 4x + 2x = 12 + 6 + 5
4x - 4x = 23
0 = 23

Answer:
D. 15
Step-by-step explanation:
I assume you know what pascal's triangle is if this is the work you must complete. If not, I have attached it below.
Now, raising (a+b) to the 6th term would expand to this, based on Pascal's triangle
![\left(a+b\right)^6 = \quad a^6+6a^5b+15a^4b^2+20a^3b^3+15a^2b^4+6ab^5+b^6](https://tex.z-dn.net/?f=%5Cleft%28a%2Bb%5Cright%29%5E6%20%3D%20%5Cquad%20a%5E6%2B6a%5E5b%2B15a%5E4b%5E2%2B20a%5E3b%5E3%2B15a%5E2b%5E4%2B6ab%5E5%2Bb%5E6)
Remember that terms are separated by addition or subtraction symbols.
The 5th term of this 7 term expansion would be 15a^2b^4. The coeffecient is 15 in this case.

Answer: y= - ( x - 5) ( x + 7)
Step-by-step explanation: The x-intercepts are at -5 and 7. when you don’t have a negative symbol before the parentheses, that indicates that the parabola will be shaped like a U. when you do, it’s shaped the opposite of a U. and now look at the equation answer.
