Answer:

  a)  C  x +x +x +3x +3x = 18

  b)  x = 2

  c)  2 cm, 6 cm

Step-by-step explanation:

a) The sum of the lengths of the sides is equal to the length of the perimeter. The appropriate equation is ...

 x +x +x +3x +3x = 18

__

b) Simplifying, the equation becomes ...

  9x = 18

  x = 2 . . . . . divide by 9

__

c) The shorter sides are x = 2 cm.

The longer sides are 3x = 6 cm.

Negative 5 is fewer than 6 less than a number k
lara [203]

Answer:

k > 1 is the solution.

Step-by-step explanation:

We are given that 'Negative 5 is fewer than 6 less than a number k', so algebraically it means that - 5 < k - 6.

Then this is a linear inequality of single variable k and we have to solve it.

Now, we have

- 5 < k - 6

⇒ - 5 + 6 < k - 6 + 6 {Adding 6 to both sides}

⇒ 1 < k

⇒ k > 1

This is the solution of the given inequality. (Answer)
