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 :))

step-by-step explanation:

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
