<h3>Given :</h3>

  • z = - 2

<h3>To Find :</h3>

  • 3 - 6(z - 2) = ?

<h3>Solution :</h3>

By substituting value of z = - 2 in 3 - 6(z - 2), we get :

\tt : \implies 3 - 6(z - 2) = 3 - 6((-2) - 2)

\tt : \implies 3 - 6(z - 2) = 3 - 6(-2 - 2)

\tt : \implies 3 - 6(z - 2) = 3 - 6(- 4)

\tt : \implies 3 - 6(z - 2) = 3 + 24

\tt : \implies 3 - 6(z - 2) = 27

\large \underline{\boxed{\bf{ 3 - 6(z - 2) = 27}}}

Hence, value of 3 - 6(z - 2) = 27.

Write an equation in standard form for:
Tasya [4]
Hello!
When finding the perimeter of a rectangle, you have to consider the properties of a rectangle. A rectangle has two pairs of equal sides where one is the width, while the other one is the length. 
Now looking back at your question, it says "... a rectangle that is x units wide" ⇒ you let the width = x ; this is the same with "y units long" ⇒ length = y. Perimeter can just be : P = 24.  
Therefore,
The equation would be:
x + x + y + y = P. 
2x + 2y = P.
(Sub in P = 24)
∴ 2x + 2y = 24. (This should be your answer.)
:) Good luck (Message me if you have any problem)
