2x + 3 + 2x + 3 + x + 2 + x + 2 = 46

write both equations twice since its a rectangle and the perimeter is the length of each side.

6x + 10 = 46

combine like terms

6x + 10 = 46
-10 -10

get rid of the 10 by subtracting on both sides

6x = 36

6 6

get rid of 6 by dividing it on both sides

x = 6

Answer:

Explanation:

Since the perimeter is 46, and opposite sides of a rectangle are equal, we know that

(x+2)+(x+2)+(2x+3)+(2x+3)=46

Combine like terms to get: 6x+10=46

Subtract 10 from both sides to get: 6x=36

Divide both sides by 6 to get: x=6.
