Acouple wants to install a square mirror that has an area of 500 square inches. to the nearest tenth of an inch what length of wood trim is needed to go around the mirror

A couple wanted to install a square mirror that has:

Area of the mirror = 500 square inches.

x = nearest tenth of an inch , length of wood needed

s = sides of square

Area = s2

500 (area) = s2  | √

x = √500

=> √ 5 x 100

=> √ 5 x √100

=> 10 √ 5

=> approximately 22.4

Since we’re looking for the nearest tenth of decimal place value, the answer is approximately 22.4

:)

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

my answer is$ 12

step-by-step explanation:

because 15 -2=12
