Answer:
4
Step-by-step explanation:
Set up ratios of corresponding sides. x+2 is to 6 as 2 is to 3:

Now cross multiply to get
3(x + 2) = 12 and
3x + 6 = 12 so
3x = 6 and
x = 2. That means that side AB, x + 2, is 2 + 2 which is 4
A:B = 2:3
A=126
B=?
126/2=63
63x3=189
A=126
B=189
A:B = 126:189
Answer: (12, 0) and (0, 8)
Step-by-step explanation:
This equation is in standard form. We can sub in a number for x to solve for y and vice versa.
Let's sub in 0 for x.

When x is 0 y is 8 giving us the coordinate (0, 8).
Now lets sub in 0 for y

When y is 0 x is 12 giving us the coordinate (12, 0)
