The perimeter of a quadrilateral (four-sided polygon) is 41 inches. the longest side is twice as long as the shortest side. the other two sides are equally long and are 3 inches longer than the shortest side. find the length of all four sides.

7, 14, 10, 10 inches

Step-by-step explanation:

x = short side

2x = longest side

x + 3 = side 3

x + 3 = side 4

x + (2x) + (x+3) + (x+3) = 41

5x + 6 = 41

5x = 35

x = 7

sides are 7, 14, 10, 10

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

correct answer:

i^31 = -i
