Answer:
g( f(2)+3) = 30
Step-by-step explanation:
<u>step(i)</u>:-
Given function g(t)=t²-t and f(x)=1+x
given f(x)=1+x
f(2) = 1 + 2 =3
<u><em>step(ii)</em></u>:-
g( f(2)+3) = g(3 + 3)
= g(6)
= (6)² - 6
= 36 -6
= 30
<u><em>Conclusion</em></u>:-
g( f(2)+3) = 30
X = 36/5
Or x = 7.2
21 + x = 6x - 15
21 = 6x - 15 - x
21 = 5x - 15
21 + 15 = 5x
36 = 5x
36/5 = x
Answer: <em>5/8, i think :)</em>
