Answer:

Step-by-step explanation:

Combine like terms. Like terms have same variables with same exponents

3m - 5n + 6m - 8n = 3m + 6m - 5n - 8n

                               = 9m - 13n

3m - 5n + 6m - 8n \\ 3m + 6m - 5n - 8n \\ 9 m- 13n

Use the functions f(x)=7x3−3x2−x+14 f x = 7 x 3 - 3 x 2 - x + 14 and g(x)=2x3+2x+5 g x = 2 x 3 + 2 x + 5 as examples to show tha
Aneli [31]

Answer:

<h3>The given set of polynomials f(x) and g(x) are closed under subtraction.</h3>

Step-by-step explanation:

Given that the functions f ad g are defined by

f(x)=7x^3-3x^2-x+14 and g(x)=2x^3+2x+5 respectively.

<h3>To  show that the set of polynomials is closed under subtraction :</h3>

Now subtract the given polynomials

f(x)-g(x)=(f-g)(x)

=7x^3-3x^2-x+14-(2x^3+2x+5)

=7x^3-3x^2-x+14-2x^3-2x-5

=5x^3-3x^2-3x+9

∴ f(x)-g(x)=5x^3-3x^2-3x+9

  • When subtracting the polynomials the variables and their exponents remains same only variation in their coefficients.
<h3>Hence the given polynomials f(x) and g(x) are closed under subtraction.</h3>

∴ f(x)-g(x)=5x^3-3x^2-3x+9 are closed under subtraction,

Hence showed.

Diano4ka-milaya [45]

Answer:

800m

Step-by-step explanation:

this would be solved using Pythagoras theorem

we are to find the base

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

600² + b² = 100²

b² = 10000 - 3600

b² = 6400

take the square root of both sides

b = 800m
