sides of triangle are (4+3) and (2+3)
or 7,5
area of triangle=1/2×7×5=35/2=17.5 cm²
area of rectangle=3×2=6 cm²
area of shaded region=17.5-6=11.5 cm²
16n+8=4
16n=4-8
16n=-4
n=-4/16
n=-1/4.

Answer:


Step-by-step explanation:
Given

Solving (a): The cost function:
From the given parameter, it shows that the number of floor has no effect on the floors.
So, represent the floors with x.
The cost function is:

Solving (b): The slope and its interpretation
A function is represented as:

Where:

By comparing:
to 

So:

<em>What it means is that, no matter the number of floors, the cost remains unchanged.</em>
