The expressions 10/12(245b−365) and 2/3(3b+6) represent the lengths of the diagonals of parallelogram WXYZ. For what value of b is WXYZ a rectangle?

b =

The value of b in WXYZ a rectangle is 1.52

For  WXYZ to be a rectangle, the diagonal must be equal. Therefore,

10/12(245b−365) = 2/3(3b+6)

2450b / 12 - 3650 / 12 = 2b + 4

2450b / 12  - 2b  = 3650 / 12 + 4

204.166666667 b - 2b  = 304.166666667 + 4

202.166666667 b = 308.166666667

divide both sides by 202.166666667

b = 308.166666667 / 202.166666667

b = 1.52431986558

b = 1.52

b = 1.52

Step-by-step explanation:

Length of diagonals of a parallelogram = and

If the given parallelogram is a rectangle,

Length of the diagonals will be equal in measure,

Therefore,

245b - 365 =

245b - 365 =

5(245b - 365) = 4(3b + 6)

1225b - 1825 = 12b + 24

1225b - 12b = 24 + 1825

1213b = 1849

b =

b = 1.52

what statement? is there an image?

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
