Answer:
14:6
21:9
28:12
Step-by-step explanation:
Given the initial ratio of 7:3, you can find equivalent ratios by multiplying the two numbers by the same factor:
7 x 2 = 14
3 x 2 = 6
14:6
7 x 3 = 21
3 x 3 = 9
21:9
7 x 4 = 28
3 x 4 = 12
28:12
Answer: -12 but could be wrong
Step-by-step explanation:
I don't know that format but I'm going to take a guess.

x^2 + 2x - 8 - 2x - 8
x^2 -16
= 2^2 - 16 = -12
