Answer:
f(2) = 32
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² + 2x + 16
f(2) is x = 2
<u>Step 2: Evaluate</u>
- Substitute: f(2) = 3(2)² + 2(2) + 16
- Evaluate: f(2) = 3(4) + 2(2) + 16
- Multiply: f(2) = 12 + 4 + 16
- Add: f(2) = 32
And we have our answer!
Answer: A
Step-by-step explanation:
The line 'd' separates the square into two triangles. Since the side lengths are equal, the angle is 45°. We need the line separating the two 90° angles, that I am going to define as 'z'. We can use the sine function.

z = 5
To solve for x, we can use sine again but for the 30 degree angle.
