ANSWER
C. 145.75 yd²
EXPLANATION
First we need to calculate the area of the four triangular faces.
The lateral surface area
The area of the base is
To find the total surface area, we add the area of the square base to the area of the 4 triangular faces.
Therefore the total surface area is

Answer:
4)x=2
5) (-3,4)
Step-by-step explanation:
4) f(x)=x^2-4x+4-4+5
f(x)=(x-2)^2+1
f(x)=a(x-h)^2+k
Axis of symmetry is x=h
h is 2, so axis of symmetry is x=2
5) f(x)=x^2+6x+9-9+13
f(x)=(x+3)^2+4
f(x)=a(x-h)^2+k
Vertex is (h,k)
So, vertex is (-3,4)
