Will give ! in rectangle abcd, ae = 3x-1 and de = 5x-7 what is the length of each diagonal? question 1 options: 3 8 16 6

If E is in the center of the rectangle, AE = DE, so
.. 3x -1 = 5x -7
.. 6 = 2x . . . . . . . add 7-3x
.. x = 3

AE = 3*3 -1 = 8
If E is in the center of the rectangle, this distance is half the length of the diagonal, so
.. the diagonal is 2*8 = 16 . . . . . . . . corresponding to the 3rd selection

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
