Answer: The answer is (d) BC + CD = BD.

Step-by-step explanation: We are given the number line and four points A, B, C and D on the line with co-ordinate -6, -1, 2 and 8 respectively.

We are to select the correct statement out of the given four.

(a) L.H.S. = AB + BC = 5 + 3 = 8,

R.H.S = AD = 14 ≠ 8.

So, this option is incorrect.

(b) L.H.S. = AB + BC = 5 + 3 = 8,

R.H.S = CD = 6 ≠ 8.

So, this option is incorrect.

R.H.S = AD = 14 ≠ 9.

So, this option is incorrect.

(d) L.H.S. = BC + CD = 3 + 6 = 9,

R.H.S = BD = 9.

So, this option is correct.

Thus, the correct option is (d).

You have six books on yourself. You notice that three of them have red covers, and three of them have blue covers, if you choose

Triss [41]

If you know you have six books in total, then calculating the probability of the other two possible outcomes should be easy.

*P that 1 will have a red cover = 3/6 (which, if you simplify it, should be equal to 1/2)
*P that 1 will have a blue cover = 3/6 (which again, if you simplify it, should be equal to 1/2)
