Answer:

Step-by-step explanation: It’s the perimeter of each shape so you add the outside of the shape up. The second question is 11.2 and 12 as the width and length. The 11.2 is the width so on the other side it is 11.2, and the length is 12 so the other side is 12. You then add them all up and get your answer.

Well I don't know !
Let's take a look and see:

The idea is that there could be more than one way
for a roll of the dice to land with the same number.

-- If the sum is from 1-4, you get the point.
There are 6 different ways for a roll of the dice to come up 1-4.

-- If the sum is from 5-8, Adam gets the point.
There are 20 different ways for a roll of the dice to come up 5-8.

-- If the sum is 9-12, Lana gets the point.
There are 10 different ways for a roll of the dice to come up 9-12.

-- The game is not fair to all three of you.
-- Lana has a distinct advantage over you.
-- Adam has a big advantage over Lana.
-- Adam has an even bigger advantage over you.
-- You are at a big disadvantage. (Notice that one of your
numbers ... 1 ... can never come up unless one of the dice
falls off of the table.)

Pls help I’ll make brainlest and give extra points

allochka39001 [22]

Answer:

p>-3 open circle going to the right

$m\leq -4$ closed circle going to the left

n<5 open circle going to the left

$h\geq 2$ closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Step-by-step explanation:

Before I answer these here are some good notes

If the inequality sign is < or > then the circle is going to be open

If the inequality sign is $\leq or\geq$ then the circle is going to be closed

If the inequality sign is facing the variable (ex: x>3) then the line is going to be going to the right

If the inequality sign is facing the constant (ex: x<3) then the line is going to be going to the left

p>-3 open circle going to the right

$m\leq -4$ closed circle going to the left

n<5 open circle going to the left

$h\geq 2$ closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle
