Answer:
B. x = 7; AB = 9, AC = 12
Step-by-step explanation:
12/4 = (x + 2)/(x - 4) (similar triangles theorem)
3 = (x + 2)/(x - 4)
Cross multiply
3(x - 4) = (x + 2)
3x - 12 = x + 2
Collect like terms
3x - x = 12 + 2
2x = 14
x = 14/2
x = 7
✔️AB = x + 2 = 7 + 2
AB = 9
✔️AC = (x + 2) + (x - 4) = (7 + 2) + (7 - 4)
AC = 9 + 3
AC = 12
These are all of the possible ratios:
- 1:3
- 8:24
-4:12
-2:6

Answer:
the answer is b i click it and it was right
y=2(3)^x
Step-by-step explanation:
Hey You!
The two are related because they both use the same three numbers. For example:
6 × 3 = 18 3 × 6 = 18
Or,
18 ÷ 3 = 6 18 ÷ 6 = 3
