<h2>
Answer: C) stars in these regions are hidden by interstellar dust grains.</h2>
Explanation:
Some areas of the Milky Way seem dark because those are areas of the galaxy that are hidden by huge columns of interstellar dust that we cannot see through the visible range of the electromagnetic spectrum (which is the range in which our eyes see).
However, to solve this problem, astronomers use telescopes that work in the range of infrared and radio waves, to observe a little more through this intersetelar dust.
Answer:
Explanation:
Simplify -3\times -5−3×−5 to 1515.
15=-2\times -20
15=−2×−20
2 Simplify 2\times -202×−20 to -40−40.
15=-(-40)
15=−(−40)
3 Remove parentheses.
15=40
15=40
4 Since 15=4015=40 is false, there is no solution.
No Solution

jack may live closer to the bookstore so it may only be 0.5 kilometers.
There are no true statements on that list at all.
