Answer:
Because there are many ways you can simplify an equation, and it will still be the same.
Answer:
3x = 95
95 ÷ 3 = 31.6666......
I used bus stop method to work this out
Therefore the estimate would be:
x = 32 or 31.7 depending on how accurate it needs to be.
You could alternatively change 95 to 96 and calculate it easily like that

Answer:
19
Step-by-step explanation:
given:
f(x)=3x²-8
g(x)=4x+1
g(-1) = 4(-1)+1
g(-1) = -4 + 1
g(-1) = -3
hence
f[g(-1)]
= f(-3)
= 3(-3)²-8
= 3(9) - 8
= 19
