Answer:
g(f(x)) = (x + 9)^2 or x^2 + 18x + 81
Step-by-step explanation:
(gºf)(x) is the "c .... " of two functions f(x) and g(x): f(x) is the input to g(x).
We start with g(x): g(x) = x^2. We replace the first x with f(x) and the second x with x + 9:
g(f(x)) = (x + 9)^2 or x^2 + 18x + 81
Answer:
Perimeter expression: 3x-3+3x+x+4
Area expression: ( (3x-3)*(x+4) ) / 2
X= 5
Step-by-step explanation:
Perimeter is all the sides added together.
Area is base times height divided by 2
If perimeter is equal to 36 set the perimeter equation to 36 and solve for x.
3 times a # (# isn't specified, so you should use a variable): 3x
result is 5: =5
Put it all together: 3x=5
