Suppose the length of each side of a

Ilya [14]

Answer:

The original side length of the square was 9 ft

Step-by-step explanation:

Consider that the square was initially of side length "x" (our unknown). Then the sides were all increased by 5 ft, and now the perimeter (addition of all four sides) of the square render 56 ft.

Let's write an equation that represents the addition of the four sides of this new rectangle, and set it equal to 56 ft. Then solve for the unknown "x":

$(x+5)+(x+5)+(x+5)+(x+5)=56\\x+x+x+x+5+5+5+5=56\\4x+20=56\\4x=56-20\\4x=36\\x=9$

Therefore, the original side of the square was 9 ft.

2x+y=2(6-2) how to solve

goblinko [34]

Answer:

x= −1 /2 y+4

Step-by-step explanation:

Let's solve for x.

2x+y=2(6−2)

Step 1: Add -y to both sides.

2x+y+−y=8+−y

2x=−y+8

Step 2: Divide both sides by 2.

2x /2= −y+8 /2 x= −1 /2 y+4
