Answer 1

Answer:125,pls mark as brainliest answer

Step-by-step explanation:  X square , Y square, Z square means that no. should be multiplied by that number

250 DIVIDED BY 2  

=125

Answer 2

Answer:

• x^2+y^+z^=250

Step-by-step explanation:

xy+yz+zx=3

(x+y+z)^2=x^2+y^3+z^2+2xy+2yz+2zx

(x+y+z)^2=250+2(3)

x+y+z=2√256

x+y+z=16

Hence the value of x+y+z=16
