Answer: The total cost would be 37.95
Step-by-step explanation:
Let f(b) = <span>3b^2+13b+4/b+4
</span>the domain of f is D = {b/ b+4#0} so b# - 4
so the undefined value of is when b = -4
For the square its 18x12 which is 216
For tge triangle its 18x7 which is 126 divided by 2 because its a triangle so 63
216+63=279yds^2
