The distance from Dan's house to Samuel's house is 4 km
The distance from Dan to Samuel house, Dan to Cindy house and Samuel to Cindy house forms a right angled triangle.
Distance from Dan to Samuel house = x, Distance from Dan to Cindy house = 3 km and Distance from Cindy to Samuel house = 5 km
Pythagoras theorem shows the relationship between the lengths of a right angled triangle.
Using Pythagoras theorem:
5² = x² + 3²
25 = x² + 9
x² = 16
x = 4 km
Hence the distance from Dans house to Samuel's house is 4 km

Answer:
<em>Leila would make a profit of $48</em>
Step-by-step explanation:
~ Knowing that there is some sort of proportion that can be formed through Leila and Jo's profit, we could form even a proportionality to compute the profit Leila makes given jo's profit of $60 ~
<em>If is is known that Leila: Jo, 4: 5, we could form such a proportion:</em>
4 5 ⇒ where x - Leila's profit knowing Jo's profit of $60
x 60
<em>Now let us solve for x, through cross multiplication:</em>
5x = 60 * 4,
5x = 240,
x =<em> profit of $48</em>
Answer:
Yes
Step-by-step explanation:
I would say yes, x is multiplied by itself to get an answer for y.
