XYZW is a parallelogram with diagonals XZ and Y W that intersect at point A. If XA = 3x, ZA = 5x - 4, and YW = 10x, find the value of x and the length of WA.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
