Answer:
The answer is D 
Step-by-step explanation:
the y is +10 
slope is -1/3
 
        
             
        
        
        
Break down the figure into 2 parts. Then use volume formula and multiply.
V=lwh
V=3x3x2
V=18ft^2
V=lwh
V=2x2x3
V=12ft^2
Then simply add.
  18
+12

The effect that  'h' have on the graph of a parabola is Horizontal shift or translation .
<h3>What is 
translation?</h3>
A translation is the movement of  a shape up, down , this can also be movement from side to side.
Even though there is movement,   its appearance remains the same in any other way, hence, h values cause left or right movement with respect to the graph.

Answer:
x = 20
Step-by-step explanation:
AE is an angle bisector, which means it cuts that triangle into 2 equal halves. So this means ∠BAE and ∠EAC should be equal to each other.
Set them equal to each other and solve for x.
∠BAE = ∠EAC
x + 30 = 3x - 10
40 = 2x
x = 20
