A table of values can be used to represent variables that are directly proportional.
The complete table of proportions is:
Given that
Let:
<em /><em> Letters</em>
<em /><em> Cost</em>
<em />
Using proportional reasoning, we have:
Where
<em /><em> ratio of proportion</em>
For the first values of C and L, we have:
Divide both sides by 10
So, the equation of proportion is:
<u>When C = 6.75, we have:</u>
Solve for L
<u>When L = 7, we have:</u>
<u>When L = 1, we have:</u>
<u>When L = 500, we have:</u>
<u>When C = 18.90, we have:</u>
Solve for L
Hence, the complete table is:

Answer:
<em>A(x) = 6x² + 26x </em>
Step-by-step explanation:
A(x) = 4x ( x + 10 ) - 2x ( 8 ) + +
A(x) = 4x² + x² + x² + 40x - 16x + 2x
<em>A(x) = 6x² + 26x</em>
