What is the length of BC¯¯¯¯¯ ? segment B C with point D between B and C. congruency markings at segment BD and at segement D C.

Arturiano [62]

Answer: segment BC = 36 units

Step-by-step explanation:

As per the given information, we have

B, C and D are three points such that

segment BC = segment BD + segment DC ... (i)

And segment BD = segment DC ... (ii)

If segment BD = 18 units

Then, segment DC = 18 units [From (ii)]

segment BC = 18 units + 18 units [From (i)]

⇒segment BC = 36 units

Hence, length of $\overline{BC}$ = 36 units

Use Pascal's Triangle to determine the second term of the expansion of (x - 2)^5

goldfiish [28.3K]

Pascal's triangle up to the 5th iteration is

$\begin{array}{cccccc}1\\1&1\\1&2&1\\1&3&3&1\\1&4&6&4&1\\1&5&10&10&5&1\end{array}$

This tells us

$(x-2)^5=\boxed{1}x^5(-2)^0+\boxed{5}x^4(-2)^1+\boxed{10}x^3(-2)^2+\boxed{10}x^2(-2)^3+\boxed{5}x^1(-2)^4+\boxed{1}x^0(-2)^5$

so the second term in the expansion is

$5x^4(-2)^1=\boxed{-10x^4}$
