Nontrivial solution of Ax D 0. 32. Given A D 2 4 4 1 6 7 5 3 9 3 3 3 5, observe that the first column plus twice the second column equals the third column.

one that is bigger than 3 1/2

5050 i think

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
