Answer: 6
Step-by-step explanation:
the area of the base is the triangle base
the area of a triangle is bh/2
that looks like a perpendicular sign in the top left so b = 3 and h = 4
so area = 3*4/2 = 6
Answer:
Two
Step-by-step explanation:
F(x)=a(x-h)^2+k
vertex is (h,k)
f(x)=1(x-6)^2-31
f(x)=1(x-(6))^2+(-31)
h=6
k=-31
vertex=(6,-31)
