which function is best represented by this graph?
F
h(x) = x2 – 3x - 9
G
h(x) = x2 + 3x – 9
H
h(x) = x2 - 6x
n(x) = x2 + 6x

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

what level of math? also i don't need to be paid if i can you.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

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.
