Can anyone tell me how to be pretty​

Which expression gives the area of the triangle shown below

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? )

Find the length of the radius of a circle with the center at -7+2i and a point in the circle at 33+11i
