To find 15, Beau found 32 = 9 and 4 = 16. He said that since 15 is between 9 and 16,15 must be between 3 and 4. He thinks a good estimate for 15 is 3+4 = 3.5. Is Beau's estimate high, low, or correct? Explain.​

Answer: His estimate was low

Step-by-step explanation:

It's true that √16 is 4 and that √9 is 3

for √15 :

It's true that √15 lies between 3 and 4

Estimated answer :

Exact answer :

Therefore, the error:

Since error is less than 0.5, his estimation was moderate, [ low ]

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
