Which equation could be used to find the perimeter of a rectangle that has a width of 12 cm and a length of 16 cm?
a. p = 2 · 12 + 2 · 16
b. p = 2 · 12 + 16
c. p = 12 · 16
d. p = 12 + 16

When you answer this can you explain

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.

Atransformation was performed on rectangle c as shown in the graph. what type of transformation was performed? does that transformation result in congruent shapes? you people
