Provide an appropriate response.Explain the error in the following: x2 + 2x - 15 = (x - 5)(x + 3)
What will be an ideal response?
The factorization yields a middle term of -2x rather than 2x:
x2 + 2x - 15 = (x + 5)(x - 3)

Solve the problem.Each customer of a photography studio pays a sitting fee of $20.(i) Complete the table to find an expression that describes the total cost (in dollars) of a photograph package plus the sitting fee if a customer pays p dollars for a photograph package. Show the arithmetic to help you see a pattern.(ii) Evaluate the expression you found in part (i) for p = 171. What does your result mean in this situation?
A. (i) 
(ii) 8.55; If the photograph package is $171, then the total cost is $8.55.
B. (i) 
(ii) 191; If the photograph package is $171, then the total cost is $191.
C. (i) 
(ii) 3420; If the photograph package is $171, then the total cost is $3420.
D. (i) 
(ii) 151; If the photograph package is $171, then the total cost is $151.
