Factor this polynomial expression.
2 + 8x + 16
OA (x+3)(x + 2)
O B. (x - 3)(x - 2)
O C. (x + 4)(x + 4)
O D. (x-4)(x-4)

C

Step-by-step explanation:

To factor x^2+8x+16, you have to find two numbers that add up to 8 and multiply to your constant, 16. 4 and 4 fit these requirements so you can factor them as (x+4)(x+4). Hope I explained it okay :)

129

Step-by-step explanation:

PEMDAS (parenthesis, exponents, multiplication / division, addition /subtraction.) I will use these as abbreviations.

8^2 + 9 (12/3*2) - 7

P: Start with P, and inside P go left to right with M/D

    D: 8^2 + 9 (4*2) - 7

    M: 8^2 + 9 (8) - 7

E: The next step is E, so I will do 8^2

64 + 9 (8) - 7

M/D: I will then multiply from left to right

64 + 72 - 7

A/S: Finall I will add and subtract from left to right.

   A: 136 - 7

   S: 129
