x^2=-36 (picture)
This equation is not possible. All numbers that are squared end up as positive. -6^2 still equals 36 as well as 6^2. Hope this helped!
Answer:
w = 21
x = 13
y = -11
z = -16
Step-by-step explanation:
Matrix subtraction is simply subtracting "corresponding" values e.g. row 1 column 1 value of one matrix and row 1 column 1 value of another matrix, and so on...
Thus, w = 17 - (-4) = 17 + 4 = 21
x = 12 - (-1) = 12 + 1 = 13
y = -3 -8 = -11
z = -2 -14 = -16
These are the values of w, x, y and z , respectively.
