Answer:
Area: 9cm²
Perimeter: 12 cm
Explanation:
Area is length x width
It's a square so length and width are the same
3 times 3 is 9
And to find the perimeter you just add the side lengths
Squares have 4 sides and the given side length is 3 so 3x4 OR 3+3+3+3 is how you get the perimeter.

Answer:
g(x) = 3
Step-by-step explanation:
Simply substitute -4 in for x in the equation (as you can see -4 takes the place of x in g(-4), so just do the same thing for all of the other x's in the equations). Therefore, g(-4) = (-4) + 7. Well, since -4 is negative and 7 is positive, you can think of it as 7 - 4, which gets you 3. Voila! 3 is your answer :)
