If f(x) = 5x + 40, what is f(x) when x = –5?

a). Model A = 7.125 ft

Model B = 7.75 ft

b). Car B is wider than Car A.

Step-by-step explanation:

a). Model A of the car is ft wide.

Model B is 93 inches wide.

Since 12 inches = 1 foot

      So, 1 inch  = foot

Therefore, 93 inches = feet

                                   = feet or feet

Length of the model A =   ft = 7.125 ft

Length of the model B =   ft = 7.75 ft

b). Now we have to compare both the models having measures ft and feet respectively.

As we ave seen in part (a), model B is more wider than model B.

Therefore, car B will be more wider.
