The top choice.
Step-by-step explanation:
If a quadratic function is a perfect square trinomial, its graph will intersect the x-axis exactly once.
Expanded, this is
There is only one value of x which makes the "two" factors equal to zero, and that is -1, where the graph touches the x-axis.

Answer:
Step-by-step explanation:
OK... You have to use this formula: <u>Y2 - Y1</u>
X2 - X1
- -2 represents X1
- 7 represents Y1
- 2 represents X2
- -5 represents Y2
<u>Y2 - Y1</u>
X2 - X1
<u>-5 - 7</u>
2 - - 2
<u>-12</u>
-2
Simplify by dividing both -12 & -2 by 2: <u>-6</u>
-1
It's either <u>-6</u> or it's just -6 by itself... Really sorry if I'm wrong...
-1
If it's 5cm x 5 cm x 5cm
Volume is a3
so 125cm
