Answer:

Step-by-step explanation:
To find this equation in standard form, first, write it in factored form. This looks like
. Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.
- Following the FOIL method, you should multiply the first terms in each binomial,
, which equals
. - Then, the outside terms,
. This equals
. - Next, the inside terms,

. - Finally, the last terms,
, this equals
.
Then, add all of the terms together
. To get the standard form, combine like terms, this comes out to
.
Answer:

Step-by-step explanation:
Given:
'C' represent total cost of lease. 'd' represents cost of sales in dollars.
Cost of 1 square foot of building = $0.75
Total area of the building = 500 square feet.
Sales tax on the total sales = 2.5%
Now, cost of 500 square feet area = Cost of 1 square foot × Total area
Cost of 500 square feet area = 
Now, sales tax is 2.5 of total sales 'd'. This gives,
Sales tax = 
Now, total cost is the sum of least amount and total sales tax.
Total cost = Least amount + Sales tax
⇒
