Find the value of the variable.​
ICE Princess25 [194]

Answer:

\large\boxed{x=3\sqrt5}

Step-by-step explanation:

Look at the picture.

ΔABC and ΔDBA are similar (AA). Therefore the sides are in proportion:

\dfrac{AB}{BC}=\dfrac{BD}{AB}

We have

AB=x,\ BC=5+4=9,\ BD=5

Substitute:

\dfrac{x}{9}=\dfrac{5}{x}             <em>cross multiply</em>

x^2=(9)(5)\to x=\sqrt{(9)(5)}\\\\x=\sqrt9\cdot\sqrt5\\\\x=3\sqrt5

Giselle wants to buy a condo that has a purchase price of $163,000. giselle earns $2,986 a month and wants to spend no more than
Alborosie
The condo costs $163,000, earns $2,986 per month, spends no more than 25% of her income, then if she pays $33,000 for the down payment, the remaining amount would be $130,000. Since 20% of the initial cost is only $32,600, she can adjust her down payment to 20.25% of the initial cost so that the annual payments would be less.
