If the side length of the base of a square pyramid is divided by 4 and the slant height is divided by 3, what is the surface area formula that represents these changes?
a. sa = n(1/8lb) + 1/16b
b. sa = n(1/24lb) + 1/16b
c. sa = n(1/24lb) + 1/4b
d. sa = n(1/12lb) + 1/4b

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
