Which characteristics are common in southern africa’s rural communities?

choose all answers that are correct.

a.
blending of traditional and modern cultures

b.
homes made of clay and thatch

c.
subsistence farming

d.
little change in village life over centuries

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
