BAC ~ DEC<br><br>x = ___ units​
sergey [27]

Given:

\Delta BAC\sim \Delta DEC

To find:

The value of x.

Solution:

We have,

\Delta BAC\sim \Delta DEC

The corresponding parts of similar triangles are proportional.

\dfrac{AB}{ED}=\dfrac{AC}{EC}

On substituting the values, we get

\dfrac{24}{56}=\dfrac{2x}{3x+5}

\dfrac{3}{7}=\dfrac{2x}{3x+5}

3(3x+5)=2x(7)

9x+15=14x

Subtract 9x from both sides.

15=14x-9x

15=5x

\dfrac{15}{5}=x

3=x

Therefore, the value of x is 3 units.

Lerok [7]

Answer:

$14,030.48

Step-by-step explanation:

We can use the following formula to solve:

A=P(1-r)^t

<em>P = principal value </em>

<em>r = rate (decimal) </em>

<em>t = time (years)</em>

<em />

First, lets change 7.3% into a decimal:

7.3% -> \frac{7.3}{100} -> 0.073

Next, plug in the values:

A=19,000(1-0.073)^4

A=14,030.48

The value will be $14,030.48
