Question

Need help with this plz!!!

Answer 1

the answer is 4.
x =-3 y= 1
-3 x 1= -3 and (-3)^2 + (1)^1 = 10
if u plug in -3 into the x and 1 into the y you get 4.

Answer 2

Answer:

$4 = [x + y]^{2}$

Step-by-step explanation:

${x}^{2} + 2xy + {y}^{2} = [x + y]^{2}$

${x}^{2} + 2xy + {y}^{2} = [x + y]^{2} \\ \\ [-3]^{2} + 2[-3] + {1}^{2} = [-3 + 1]^{2} \\ \\ 9 - 6 + 1 = [-2]^{2} \\ \\ 4 = 4$
