131+-5 is equal to 126
To make it less confusing it’s just 131-5
x+y=18897
x=y+673
2y+673 = 18897
2y = 18224
y= 9112
x = 9112+673 = 9785
9112 + 9785 = 18897
so one country is 9112 and the second country is 9785
Answer:
42
Step-by-step explanation:
g(4) = 2x^2+5
= 2(4)^2+5
= 2(16)+5
= 32+5
= 37
f(g(4)) = 21+3sqrt(x+12)
= 21+3sqrt(37+12)
= 21+3sqrt(49)
= 21+3(7)
= 21+21
= 42
76766 is the correct answer
