Mathematics

Answer:

x = 17

Step-by-step explanation:

The diagonals of a rectangle are congruent, thus

BD = AC, that is

2x - 12 = x + 5 ( subtract x from both sides )

x - 12 = 5 ( add 12 to both sides )

x = 17

What is the sum of an infinite geometric series if the first term is 156 and the common ratio is 2⁄3?
Zanzabum

Answer:

<h2>B. 468</h2>

Step-by-step explanation:

We have

a_1=156,\ r=\dfrac{2}{3}

If |r| < 1, then the formula of a sum of an infinite geometric sequence is:

S=\dfrac{a_1}{1-r}

Substitute:

S=\dfrac{156}{1-\frac{2}{3}}=\dfrac{156}{\frac{1}{3}}=156\cdot\dfrac{3}{1}=468
