Answer:
D: A(x) = 4x² + 40x + 96
Step-by-step explanation:
Dimensions of photo is;
Length; L = 12 inches
Width; W = 8 inches
Now, this picture is surrounded by a frame that is "x" inches wide. Thus, new dimensions are;
L_new = 12 + x + x = 2x + 12
W_new = 8 + x + x = 2x + 8
New area is;
A_new = (2x + 12) × (2x + 8)
A_new = 4x² + 24x + 16x + 96
A_new = 4x² + 40x + 96

Answer:
cumulative cell phone cost after 18 months = 922.4
Step-by-step explanation:
We are given the line of best fit for the data as;
C = 51m + 4.4
where;
C is the cumulative cell phone cost
m is the number of months.
Now, we are told that m = 18 months
Thus;
C = 51(18) + 4.4
C = 918 + 4.4
C = 922.4
