Answer:
I think it is the last one
Step-by-step explanatio
union=( -2,-1,0,1,2,5,7,8) intersection= -1,1
Step-by-step explanation:
J=(x+4)²
K=(8-x)
X=5
=J+3k
=(x+4)(x+4)+3(8-x)
=(x²+8x+16+24-3x)
=25+25+40
=90
Alternatively:
J=(5+4)²
J=81
K=8-5
K=3
J+3k
81+3(3)
81+9
90
Option A. 150 m 3 is the correct one
