Answer:

Dimensions of rectangle = <u>23 cm x 5 cm</u>

Step-by-step explanation:

<u>Equations we can form</u>

  • Perimeter of 56 cm

⇒ 2L + 2W = 56

⇒ L + W = 28

  • Length is 8 more than 3 times its width

⇒ L = 3W + 8

<u>Substitute in previous equation</u>

⇒ 3W + 8 + W = 28

⇒ 4W = 20

⇒ W = <u>5 cm</u>

<u></u>

⇒ L = 28 - 5 = <u>23 cm</u>

Write each of the following expressions without using absolute value: |z−6|−|z−5|, if z&lt;5
abruzzese [7]

Answer:

The answer is <em>1</em>.

Step-by-step explanation:

Given the expression:

|z-6|-|z-5|,\ if\ z

To find:

The expression without absolute value.

Solution:

First of all, let us learn about the absolute value function:

y = f(x) = |x| =\left \{ {{x\ if\ x>0} \atop {-x\ if\ x

i.e. value is x if x is positive

value is -x if x is negative

Here the given expression contains two absolute value functions:

|z-6| and |z-5|

Using the definition of absolute value function as per above definition.

|z-5| =\left \{ {{(z-5)\ if\ z>5} \atop {-(z-5)\ if\ z

|z-6| =\left \{ {{(z-6)\ if\ z>6} \atop {-(z-6)\ if\ z

Now, it is given that z < 5 that means z will also be lesser than 6 i.e. z < 6

So, given expression |z-6|-|z-5|,\ if\ z will be equivalent to :

-(z-6) - (-(z-5))\\\Rightarrow -z+6 +z-5 = \bold{1}

So, the expression is equivalent to <em>1</em>.

How do you subtract integers?<br> like -81-(-34)
DedPeter [7]

Answer:

-47

Step-by-step explanation:

For this problem, we can use the rule "two negatives make a positive".

-81-(-34)

= -81 + 34

If you subtract 34 from 81, you find the opposite positive/negative answer.

81 - 34 = 47

Change all of the positive/negative signs:

-81 + 34 = -47
