Answer:
x=-8
Step-by-step explanation:
the equation is in standard form of y=ax^2+bx+c
so, to find the vertex, or axis of symmetry do -b/2a.
-16/2(1)=
-8
area of triangle = 1/2(4) (3) = 6 units^2
area of trapezoid = 1/2(4 + 6) (4) = 20 units^2
area of figure = 6 + 20 = 26 units^2
answer
a. 26 units^2

Answer:
Step-by-step explanation:
12 - 12x = -6x + 48
Add 12x to both sides. That eliminates the x term on the left side.
12 = 6x + 48
Subtract 48 from both sides. That eliminates the constant term on the right side.
-36 = 6x
x = -6
