Step-by-step explanation:

f.g(x) = f(x+2)

=(x+2)2 -1

=(x2+2*x*2+4)-1

=x2+4x+4-1

=x2+4x+3

Answer:

Step-by-step explanation:

P = 4 + 6 + (3y - 2) Remove the brackets

P = 10 + 3y - 2 Combine

P = 8 + 3y

Note 3y must be less than 8. That's because 2 sides of any triangle must be larger than the 3rd side or else you don't have a triangle.
