Find f(2) given f(x) = 3x^2 + 2x + 16​
horrorfan [7]

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>

  1. Substitute:                    f(2) = 3(2)² + 2(2) + 16
  2. Evaluate:                       f(2) = 3(4) + 2(2) + 16
  3. Multiply:                        f(2) = 12 + 4 + 16
  4. Add:                              f(2) = 32

And we have our answer!

For number 7:

a) The sum of the adjacent angles is 180. Because if its any three angles thats half of the angles all together 3/6 = 180/360. 

b) The sum of the angles in the center is 360 degrees. Because 60 x 6 = 360.

c) The unknown angles (center angles) are 61.25 degrees. 

For number 8 (bonus):

It's C) 90 Degrees, because it's a right angle. 

Hope this helps :)
