No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect
<h3>Perpendicular lines</h3>
In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:
For the slope of lm:

For the slope of ln:

For the slope of mn:

- If any of the two lines is perpendicular, hence the triangle lmn is right-angled.
- To check, we will take the product of the slopes and see if it is equivalent to -1.
Product of slope lm and ln

Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect

45x+180=900
Where x is the number of weeks
45x+180-180=900-180
45x=720
X=16
It will take 16 more weeks to save the rest of the money.
An amount of $ 2392 are withheld in a year. (Correct choice: A)
In this question we must determine the amount of money that is withheld in a year. By considering a year as a 52-week period, the total money to be withheld in a year is equal to the product of the weekly money that is withheld and the number of weeks in a year, that is to say:
C = (52 weeks) • (46 USD/WEEK)
C = 2392 USD
An amount of $ 2392 are withheld in a year.
Hence, A is the answer.

The total rent payed for the apartment =
$1,370
<h3>Calculation of move-in cost </h3>
The complete question:
How much would you pay in move-in costs for the two-bedroom hometown apartment if you pay first and last month's rent, a $185 security deposit, and a 30 percent fee to the rental agent? round to the nearest dollar
2 bedroom hometown: $515 plus utilities
$1,515 $1,370 $1,245 $855
The cost of 2 bedroom apartment = $515 ×2 = $1,030
The security deposit= $185
The rental agent fee = 30/100× 515
= 15,450/100 = $154.5
Therefore the total rent payed for the apartment
= $1,030 + $185 + $154.5
= $1,369.5
~ $1,370
