Answer:
180 square inches
Step-by-step explanation:
First off since the square will be easiest to do
a=a^2
a=6^2
a=36
now for the triangles
a= height of triangle * base/ 2
a= 12*6/2
a= 36
and since there is 4 of the triangles we multiply 36 by 4
=144
now we add 144 to 36 and we have the total
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) Find the value of f(-3)
we have

we know that
f(-3) is the value of the function f(x) for x=-3
so
substitute the value of x=-3 in the function to find f(-3)



Part 2) Find the value of g(3)
we have

we know that
g(3) is the value of the function g(x) for x=3
so
substitute the value of x=3 in the function to find g(3)
