Answer:
√a^3−7-4
Step-by-step explanation:
Replace all occurrences of + − with a single −. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1⋅ −1= −1
From the ratio given you can determine that m is proportional to 1/(r^3). You can write this as m = k * 1/(r^3), k being your constant of proportionality. Then use this to calculate the next parts of the question.
The last one is the right answer
Find the Greatest Common Factor (GCF)
GCF = 2
Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2(16x/2 + 42y/2)
Simplify each term in parenthesis
<u>C. 2(8x + 21y) </u>
