Answer:
x < -1 or x > 9
Step-by-step explanation:
Add 3 to both sides.
Simplify.
Divide both sides by 10.
Simplify.
Apply absolute value rule: If 
then 
or 
or 
Add 4 to both sides.
Simplify.
Add 4 to both sides.
Simplify.
Combine the intervals.
or
F(x)=x^2+2x+1 & g(x)=3(x+1)^2
now, f(x)+g(x)
=x^2+2x+1+3(x+1)^2
=x^2+2x+1+3(x^2+2x+1)
=x^2+2x+1+3x^2+6x+3
=4x^2+8x+4<===answer(c)
next:
f(x)=x^2-1 & g(x)=x+3
now, f(g(x))=(x+3)^ -1
=x^2+6x+9-1
=x^2+6x+8<====answer(b)
i solve two of ur problems.
now try the 3rd one that is similar to no. 1
and try the last two urself.
Answer:
