Answer:
7x +1
Step-by-step explanation:
If A to C is 12x + 3, And A to B is 5x - 2 then you subtract the polynomials from each other!
12x- 5x = 7x
3 -2 = 1
So the answer is 7x +1!

The answer that u wrote on the paper is correct
Answer:
-45
-26x+30
Step-by-step explanation:
So first you let's divide this equation into three parts.
Part one -9x(5x+4)
- Step one: you have to distribute the -9x to the numbers in the parentheses. That would leave us with a -9x*5x = -45 and -9x*4 = -36x
- Step two: Put the answers together. That would leave us with -45-36x.
Part two 10(x+3)
- Step one: you have to distribute the 10 to the numbers in the parentheses. That would leave us with a 10*x = 10x and 10*3 = 30
- Step two: Put the answers together. That would leave us with 10x+30
Part three solve
- Step one: combine and put together what you have solved for. That would leave us with a -45-36x+ 10x+30
- Step two: combine like terms. The like terms here are -36x and 10x. When you combine them you would get -26x.
- Step three: Write the equation in standard form. Therefore the answer is -45-26x+30.

Answer: cross-sectional study
Step-by-step explanation:
- A cross-sectional study is a kind of research study in which a researcher collects the data from many different persons at a single point in time.
- In this study researcher observes the variables without influencing them.
Here, A research company uses a device to record the viewing habits of about 2500 households (that includes different persons such as adults , children and seniors )
The data collected today(at a single point in time).
If it is used to determine the proportion of households tuned to a particular children's children's program.
The type of observational study is described in the problem statement : "cross-sectional"
