Answer:
Length: (x - 4) meters
Step-by-step explanation:
x² - 16
x² - 4²
(x - 4)(x + 4)
Answer: 9x^2 - 6x + 8
Step-by-step explanation:
(9x^2 - 2x + 7) - (4x - 1) Subtract like terms
The term 9x^2 doesn't have any other term so it will stay alone.
-2x - 4x = - 6x
7 - (-1) = 8
Put them together to get 9x^2 - 6x + 8
Given:
h = melting point of helium
j = melting point of hydrogen
k = melting point of neon
Number of values = 3
Therefore, the average is
(Sum of values)/(Number of values) = (h+j+k)/3
Answer:
The average melting point of helium, hydrogen, and neon is
(h+j+k)/3
