Answer:
40.8
Explanation:
Since A, B, and C are collinear, we know that the distances between them must add up to the total length of the line. In other words, we can set up the equation:
AB + BC = AC
Substituting the given values, we get:
(x+2) + (4x+4) = 50
Combining like terms, we get:
5x + 6 = 50
Subtracting 6 from both sides gives us:
5x = 44
Dividing both sides by 5 gives us:
x = 8.8
Substituting this value back into the equation for BC, we find that BC = 4(8.8) + 4 = 36.8 + 4 = 40.8. Therefore, the value of BC is 40.8.
