Answer:
C.
Step-by-step explanation:
We can off-the-bat eliminate choices A and B, because the first part of the quadratic formula is a -b. Therefore, the value for b in the quadratic has to be a positive, because the value in the formula is negative. This leaves us with choices C and D. If you look at the discriminant, you will see that our <em>a </em>in the quadratic formula is 3, so your answer choice is C.

- Substitution and Evaluation
Step-by-Step Explanation:
Step 1: Define
h(x) = -49x - 125
h(-67)
Step 2: Solve
1. Substitute: h(-67) = -49(-67) - 125
2. Multiply: h(-67) = 3283 - 125
3. Subtract: h(-67) = 3158

Area of Composite Shapes</h2>
To find the area of composite shapes, we can break the bigger shape down into small, simpler shapes, and find the sum of their areas.
For this triangle, we will need to know the formula to find the area of a triangle:

<h2>Solving the Question</h2>
The given shape can be seen as one large triangle with a little triangle cut out of it. To find the shaded region, we can:
- Find the area of the large triangle
- Find the area of the little triangle
- Subtract the area of the little triangle from the large triangle
<h3>Area of the Large Triangle</h3>

⇒ Plug in the values given for the base and height:

<h3>Area of the Small Triangle</h3>

⇒ Plug in the values given for the base and height:

<h3>Subtract the Area of the Small Triangle from the Area of the Large Triangle</h3>
