Find, in radical form, the length of a diagonal of a square if the perimeter of the square is 20.

Step-by-step explanation:

one side of the square = 20/4 = 5units

By PT,

diagonal = ±√(5^2 + 5^2) = 5√2 or -5√2 (rej since diagonal > 0)

therefore diagonal length is 5√2 units.

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

i believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get
