Answer:
Proportionality Constant = k = 
Step-by-step explanation:
Equation is:

=> 
Comparing it with
, where k is the proportionality constant, We get:
Proportionality Constant = k = 
N= -4
-4/2+5=3
-2+5=3 you have to subtract the 5 from three first and then multiply the answer by 2 to get n
Answer:

Step-by-step explanation:
So we have:

First, distribute:

Combine like terms:

Add:

So, in the a+bi format, we will have:

Given:
Each right triangular tiles has the leg measures of 5.2 cm and 6 cm.
There are 150 tiles in the mosaic.
To find:
The area of the mosaic.
Solution:
We know that, the area of a triangle is:

So, the area of Each right triangular tile is:



There are 150 tiles in the mosaic. So, the area of the mosaic is:


Therefore, the total area of the mosaic is 2340 cm ².
