Answer:
<h2>A = 225 in²</h2>
Step-by-step explanation:
The formula of an area of a square:

<em>s</em><em> - side</em>
The formula of a perimeter of a square:

<em>s</em><em> - side</em>
<em />
We have a perimeter

Substitute:
<em>divide both sides by 4</em>

Put it to the formula of an area of a square:

For this case, the first thing we must do is define a variable.
We have then:
x: total sales for the week
We now write the equation that models the problem.
We have then:
p (x) = 0.035x + 300
Answer:
a function, p (x), which can be used to determine his pay for the week is:
p (x) = 0.035x + 300
<h2>

</h2><h3>This algebraic expression can be formed with the given data.</h3>
Answer:


Step-by-step explanation:
the expression (f*g)(x) can be expanded as follows

since 
Hence

also the expansion for (f-g)(x) is express as

also since
then when we substitute values, we have

For this type of operation kindly note the below expansions




Well if his car goes 617.3 miles, and he goes 41 miles per gallon
what the gallons will be
divide 617.3 by 41
=15.056
so his car used ~ 15.06 gallons of gas (i rounded the answer, if you want, you can put the full thing)
I hope this helps
