Ответ:
A.) 10x + 15
Step-by-step explanation:
You would distribute (multiply) the 5 to the 2x which would then make it 10x and you would distribute (multiply) the 5 to the 3 which would then make it 15. Because the 5 is a positive number the sign stays the same.
Therefore, 10x + 15 is your answer.
Ответ:
Sample Response: Although 6 and 3 are on opposite sides of sea level, or 0, they are not opposites because they are unequal distances from 0.
Step-by-step explanation:
3 is 3 units above 0 on a vertical number line.
–6 is 6 units below 0 on a vertical number line.
3 is not the opposite of –6.
Opposites are equal distances from 0.
