n - 7 = 21, n= 28 should be right bc the difference of 28 and 7 is 21
Answer:
Collection of soil samples would be my guess
Step-by-step explanation:
Remote sensing means taking in info from far away and you cant really take soil samples from far away.
remote sensing
the scanning of the earth by satellite or high-flying aircraft in order to obtain information about it. not always in the sky and not always on earth
The sum of the function will be (r – s)(x) = –2x² + x – 3, The difference of the function will be (r – s)(x) = –2x² + x – 3, and The product of the function will be (r × s)(x) = 2x³ – 6x².
The complete question is attached below.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The functions are given below.
r(x) = x – 3
s(x) = 2x²
The sum of the function will be
(r + s)(x) = x – 3 + 2x²
(r + s)(x) = 2x² + x – 3
The difference of the function will be
(r – s)(x) = (x – 3) – 2x²
(r – s)(x) = –2x² + x – 3
The product of the function will be
(r × s)(x) = (x – 3) (2x²)
(r × s)(x) = 2x³ – 6x²
