Answer:
49
Step-by-step explanation:
Put the variable values in place of the corresponding variables, and do the arithmetic.
x² +3(x +y) =
5² +3(5 +3) = 25 +3(8) = 25 +24 = 49
We can see that
both lines intersects at origin
so, the solution is x=0 and y=0
now, we will check each options
option-A:
now, we can set them equal
and then we can solve for x
now, we can find y
so, solution is x=0 and y=0
so, this correct...........Answer
