-k+8k
7k. Is the answer
mamaluj [8]3 years ago

Answer and Step-by-step explanation:

We are given the terms -1, k, -1, -1, and 8k.

<u>Here is where those terms are found.</u>

-1(<u>k</u>) -1( -1(8k) )

<u>Distribute all of the negative ones.</u>

-k -(-8k)

-k + 8k   _*

* How did we get positive 8k?

- When multiplying two negative numbers, which in this case was -1 and -8k, the result is positive. Thus, giving us positive 8k.

<u>Now, combine like terms.</u>

7k

The answer is 7k.

17. The perimeter of each face of a Rubik's cube is
romanna [79]

A Rubik's cube is, well, a cube.

That means that each if its faces is a square, a quadrilateral with four right angles and four sides if the same length.

If the length of one side is x,

4x=22.2

x=5.55 centimeters.

Hope this helps!

Your fortune is "All your hard work will finally pay off."

5(k+5)+4&lt;21+6k what is the answer
Temka [501]
Solve whats in the parentheses first
5k+25+4<21+6k

5k+29<21+6k

plug in a number in k for both sides
5(1)+29<21+6(1)
5+29<21+6
34<27

5(2)+29<21+6(2)
10+29<21+12
39<33

so 5(k+5)+4 is greater than 21+6k

Rewrite the following statements less formally, without using variables. Determine, as best as you can, whether the statements a
Anni [7]

Answer:

The answer is given below

Step-by-step explanation:

a) Let u and v be real numbers. The sum of u and v = u + v and the difference between u and v = u - v.

u + v < u - v means the sum of two real numbers is less than the difference between the two numbers.

There exist two real numbers such that their sum is less than the difference between them

This is true when atleast one of the numbers is negative, for example u = 2 and v = -2

u + v = 2 + (-2) = 0 , u - v = 2 - (-2) = 4

u + v < u - v.

b) Let x be a real number and x² be the square of the real number

x² < x means that the square of a real number is less than the real number

We can rewrite the statement as: There exist a real number such that its square is smaller than itself.

The statement is true for x is between 0 and ±1

E.g. for x = 1/2, x² = (1/2)² = 1/4

1/4 < 1/2

c) Let n represent all positive integers. n² is the square of n.

n²≥n means that the square of n is greater or equal to n.

We can rewrite the statement as: For all positive integer numbers, the square of the number is greater than or equal to the number itself

The statement is true.

1² ≥ 1, 2² ≥ 2 e.t.c

d)  Let a and b be real numbers. The sum of a and b = a + b. |a| is the absolute value of a and |b| is the absolute value of b

|a+b|≤|a|+|b| means the absolute value of the sum of two real numbers is less than or equal to the sum of their individual absolute value.

We can rewrite the statement as: For two real numbers, the absolute value of their sum is less than or equal to their individual absolute value sum.

This statement is true for all real numbers.
