Sam is a little fish. He lives in the sea. He is very lonely. He wants to have a friend. The friend looks like him. Sam sees an ink fish. The ink fish has eight legs. He doesn't look like Sam. So Sam goes away. Sam meets a shark. He wants to say hello to the shark. The shark opens his big mouth. Sam runs away quickly. Sam is tired and hungry. He wants to have a rest. Then he sees a round fish. She says to him. "Hello! Would you like to be my friend?" Sam answers: "Of course! But you are round. I am flat." The round fish days: "But we are both fishes."
Sam thinks and says, "You are right. Let's be friends." They become good friends.
Answer: x = -1
Step-by-step explanation:
You are trying to figure out what the missing number is that will make 4
so we know that only 2 plus or multiplied by 2 can = 4
and because 2 is outside the parentheses it has to be multiplication meaning that x + 3 has to equal 2
4 = 2(x+3)
4 = 2 ( -1 + 3)
4 = 2 (2)
2 * 2 =4
4 = 4
Hello!
To find the area of a circle you do
Where r stands for radius.
The radius is just half the diameter
So you put that into a calculator and get 113.1
Hope this helps!
if the cylinder has a diameter of 4, then its radius is half that, or 2.

Answer:
1 Shirt costs $12.50
Step-by-step explanation:
First, set up an equation
18x=12x+75
Subtract 12x from both sides
6x=75
Divide both sides by 6
x=12.5
