Sorry hun I’ve never learned that
C,D and F are correct.
C is what you would think of when reading it, you walked 12 and walked 1/4(12) more.
12 + 12(1/4) =
12 + 3 =
15
D is equal to C when simplified,
12(1+1/4) =
12 + 3 =
15
F is the same as the D, it just simplified the numbers in the parenthesis
12(1+1/4) =
12(4/4 + 1/4) =
12(5/4) =
15
Answer:

Step-by-step explanation:



Answer:
-66
Step-by-step explanation:
- 13, ____, -119
first, find the common difference:
-13 - (-119) = 106

so, the common difference is 53.
now, subtract 53 from -13:
-13 - 53 = -66
Answer:
4(b-6)=b^2
Step-by-step explanation:
