5y^2-3y+6 when y = -1

answer is 14

explanation

5×-1^2=5

-3×-1= 3

+6=

5+3+6=14

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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.
