Question

AB≅BC≅CD≅DE, AD = 8x - 4, AB = x + 2 solve for AB

Answer 1

Answer:

20/7 units

Step-by-step explanation:

As given that:

• AD = 8x - 4
• AB = x + 2

and AB≅BC≅CD≅DE, we can think of a quadrilateral has four equal sides or it would be a square. Using the property in a square, we can conclude that:

• AB = AD or,

<=> 8x - 4 = x + 2

<=> x = 6/7

So the length of side AD is:

8*6/7 - 4 = 20/7 units

Answer 2

Just solve for , then substitute back into either expression and calculate either BC or AD. The other one is then the same amount.

The one about the square is the same thing except you don't care how the figure is named because all 4 sides are equal anyway. Just set the two expressions equal to one another and then solve for
