Answer:
d² ≥ 17
Step-by-step explanation:
First round 6254 to 6000 then multiply it by 2.
6,254=6,000x2=12,000
If you need help on the multiplying bit here is how you do it:
First take the whole numbers so 6 and 2. Next multiply them. 6x2=12. Then all you do is add the zeros. So in this case there are three zeros so 12,000 is your estimated answer.
