Answer:
y=8/5x-11
Step-by-step explanation:
Answer:
19.14
Step-by-step explanation:
You have a half circle and a square, look at them separate then add for the area.
Circle
Your radius is half the diameter, so 4/2
Radius = 2
This is for the entire circle, half of that would be 3.14
Square
Add them both together for a total area of 19.14 square miles
Answer:
SA = 788cm^2
Step-by-step explanation:
<u>pink one:</u>
length- 5
width- 6
height- 20
surface area- 500
<u>purple one:</u>
length- 4
width- 6
height- 12
surface area- 288
<u>total surface area:</u>
500 + 288 = 788
SA = 788cm^2
GOOD LUCK!!!! You'll do amazing <3
X=15
Collect like terms
8x-10x=x-45
Move the variable to the left
-2x=x-45
Collect like terms again
-2x-x=-45
Divide both sides by -3
-3x=-45
Answer is x= 15
The reason for this has to do with finding the area of a square. When you are looking for the area of a square, you use the rectangle formula (since a square is also a rectangle).
The formula is Area = Length * Width
However, since in a square, the length and width are the same, both get changed to the word "Side". As a result, we get the following formula.
Area = Side * Side
This can be simplified to:
Area = Side^2.
Since each number to the second power also shows the area of a square with that given length sides, it can also be called "squared".
