Answer:

Step-by-step explanation:
we know that
In a parallelogram the diagonals bisect each other
The figure XYZW is a parallelogram
so
VW=VY
VX=VZ
<em>Find the value of b</em>
VW=VY
substitute the given values

solve for b

Find the length of YW
----> by addition segment postulate

substitute the value of b

The equivalent expression for (x + 4)^5 is 
The expression is given as:

To expand the expression, we make use of Pascal triangle, where:
5:= 1 5 10 10 5 1
So, we have:

Evaluate the exponents

Evaluate the products

Hence, the equivalent expression for (x + 4)^5 is
