The perimeter of (the distance around) abcd is 66, and dc is twice as long as cb. how long is ab?

Step-by-step explanation:

we know that

In this problem ABCD is a rectangle

so

DC=AB

BC=AD

Let

BC ---> the length of rectangle

DC ---> the width of rectangle

we know that

The perimeter of rectangle is equal to

we have

so

simplify

----> equation A

----> equation B

substitute equation B in equation A

Solve for BC

Combine like terms

Divide by 3 both sides

Find the value of DC

---->

Remember that

DC=AB

therefore

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
