Which expression is equivalent to startroot negative 108 endroot minus startroot negative 3 endroot?

Step-by-step explanation:

we have the expression

we know that

so

Remember that

substitute

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

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.
