If AC = 52, AB = 8x + 8, and BC = 2x + 4, then the length BC is
1 answer:
Answer:
12
Step-by-step explanation:
AC = AB + BC
Since we know what each variable equals, we can write out the equation as shown:
52 = 8X + 8 + 2X + 4
Combining like terms:
52 = 10X + 12
Subtract 12 from both sides:
40 = 10X
Divide by 10:
X = 4
Now that we know X, we can figure out BC
BC = 2(4) + 4
BC = 8 + 4
BC = 12
Therefore BC is 12.

Your answer is 1/5 Hope this helps :D
The ratio would be 2:6 or 1:3 in its simplest form.
For twelve jerseys it would be $210
(8 - 3i)(2 - 7i)=
16 x -56i - 6i + 21i^2
16 x -50i - 21
