I’ll explain part A and you can apply it to the other parts. The functions f(x), g(x), and m(x) are all equivalent to the given polynomials. So when it asks for f(x) + [g(x) - m(x)] you plug them in. The answer to Part A is 3x^2 +5x - z + [5x^2-3x+z - 2x^2 - 2x]. Combine the like terms (3x^2+5x^2-2x^2 = 6x^2 (because 3+5-2=6)) and so on until you’ve simplified it as much as possible!
2x + 5 - 6x + 21 = 2(3x - 5) - 4
distribute
2x+5 -6x +21 = 6x-10 -4
combine like terms
-4x +26 = 6x -14
add 4x to each side
26 = 10x -14
add 14 to each side
40 = 10x
divide by 10
4 =x
The answer is 13 square units :)

Answer:
1024
Step-by-step explanation:
so first you would do 2^10 and 2^20
2^10 = 1024
2^20 = 1048576
then you would just divide 1048576 by 1024
1048576 / 1024 = 1024
