Find a set of columns that fo11n a basis for the column space of each of the following matrices. Give the rank of each matrix. Also find a basis for the null space of each matrix. a) [-3 6 5 -10]
b) [2 1 1 1 2 1 7 5 4]
c) [ 1 1 0 0 1 1 0 0 1 1 0 1 1 0 1 0 0 1 1 1 1 1 0 0 1]
d) [1 1 1 0 1 0 1 0 1 0 2 1 2 -1 2 -1 1 -1 2 -1 1 2 1 1 1]

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
