I need help with this problem

4. ∆KLM

Step-by-step explanation:

QR corresponds to KL,

QR/KL = 36/24 = 3/2

RS corresponds to LM,

RS/LM = 45/30 = 3/2

QS corresponds to KM,

QS/KM = 48/32 = 3/2

Therefore,

∆QRS ~ ∆KLM

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
