Answer:
f(f(x)) = 27
+ 18x² + 4
Step-by-step explanation:
To find f(f(x)) substitute x = f(x) into f(x) , that is
f(3x² + 1)
= 3(3x² + 1)² + 1 ← expand parenthesis using FOIL
= 3(9
+ 6x² + 1) + 1 ← distribute parenthesis by 3
= 27
+ 18x² + 3 + 1 ← collect like terms
= 27
+ 18x² + 4
Answer:
x=-31/2
Step-by-step explanation:
Let's equate the equation to zero
-3(4x+5)-2(-5x+8)=0
-12x-15+10x-16=0
Collect like terms
-12x+10x-15-16=0
-2x-31=0
Add 31 to both sides
-2x=31
Divide both sides by-2
x=-31/2
Answer:
the answer is 2.51<2.511
Step-by-step explanation:
Simplifying then comparing both terms 2.512.51 and 2.5112.511, 2.512.51 is less than 2.5112.511, which means that the first term is less than the second term.
