Diego has 81 square inch tiles. He wants to use them to make a square mosaic. How long can each side of the mosaic be

s= 9

Step-by-step explanation:

Diego has 81 square inch tiles. He wants to use to make a square mosaic.

Area of the tile = 81 square inches

We know , area of the square = s^2

where 's' is the side of the square

Area is s²

Plug in 81 for area and solve for 's'

Take square root on both sides

s= 9

i hope this helps

have a great day :))

you answer is a

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
