If a x 10^n is scientific notation, then a must be between 1 and
Yanka [14]

Answer:

  A)  10

Step-by-step explanation:

In the US, a number in scientific notation will have a mantissa (a) such that ...

  1 ≤ a < 10

That is, the value of "a" must be between 1 and 10 (not including 10).

_____

<em>Comment on alternatives</em>

In other places or in particular applications (some computer programming languages), the standard form of the number may be a×10^n with ...

  0.1 ≤ a < 1

In engineering use, the form of the number is often chosen so that "n" is a multiple of 3, and "a" is in the range ...

  1 ≤ a < 1000

This makes it easier to identify and use the appropriate standard SI prefix: nano-, micro-, milli-, kilo-, mega-, giga-, and so on.

Answer:

The other factor is 5x-2

Step-by-step explanation:

Using the factorisation method:

Two numbers that multiply to give -10 and add to give +3:

+5 and -2

5x^{2} +5x-2x-2

5x(x+1) -2(x+1)

(x+1)(5x-2)

So the other factor is 5x-2

I'm not sure about the second part of the question but I hope you understood how to deal with the first part.
