A. 9 and 10
B. 6 and 7
C. 7 and 8
D. 8 and 9

Answer 1

Hi! I can help just give me a minute :)

Answer 2

Ok

Answer 3

hint, \(7^2=49\)

Answer 4

Okay, now in order to solve this, you need to find the perfect square of each number.

If you don't know what a perfect square is, it is the number being squared. like @satellite73 just showed you. You multiply the number twice.

\[9^{2}\] = 81.

\[10^{2}\] = 100.

Does 57 lie between 81 and 100 @nbarrera?

Answer 5

No

Answer 6

Correct! So that means A is NOT a possible answer. Let's move on to B

\[6^{2} = 12\]

\[7^{2} = 49\]

Does 57 lie between 12 and 49 @nbarrera?

Answer 7

no

Answer 8

Correct again! Now we know A and B are not possible answer. Let's move on to C!

\[7^{2}=49\]

\[8^{2}=64\]

Does 57 lie between 49 and 64 @nbarrera?

Answer 9

Yay! You are right! Great job!

Answer 10

And C is the correct answer thx :)

Answer 11

Np @nbarrera :)
