Answer:
6 × 5
Step-by-step explanation:
If you want to reduce the fraction 12/30, you want to find the greatest common factor of 12 and 30. We can find that by looking at the prime factorization of each number.
12 = 2·2·3
30 = 2·3·5
The greatest common factor is 2·3 = 6. This means ...
![\dfrac{12}{30}=\dfrac{12}{6\times5}](https://tex.z-dn.net/?f=%5Cdfrac%7B12%7D%7B30%7D%3D%5Cdfrac%7B12%7D%7B6%5Ctimes5%7D)
The product of interest is 6 × 5.

<em>Additional comment</em>
Any of the factor pairs of 30 could be used. Only the one shown is useful for reducing the fraction to lowest terms.
30 = 1×30 = 2×15 = 3×10 = 5×6
Answer:
B
Step-by-step explanation:
When a polynomial is in standard form, it is arranged in the order of largest power first, followed by the next largest, and then so on. The only polynomial here that follows this rule is the second one, or choice B. Hope this helps!

Step-by-step explanation:
√4 is equal to 2
This is because 4 is a square number, 2 x 2 = 4
4.5 times 10^10
1. Multiply 5times ten to the third
2. Multiply 9 times ten raised to the seventh
Then multiply them together
