The area of the non-shaded areas is about 63.6m. Which means the shaded area is about 17.4m. This was quite a difficult problem, but I believe this is the answer.
Answer:
y+4=-36 and the answer is y=-40
Step-by-step explanation:
So the word is means equals, meaning we can change it to say
"y more than 4 = -36
and more than means addition so we can put a plus sign there and we get
y+4=-36
then to solve this equation we need to get y by itself on one side and to do that we can move the 4 to the other side by subtracting it on both sides to cancel out the addition and we get y=-40
I hope this helps and please don't hesitate to ask if there is anything still unclear!
Answer:
You can solve this with common sense, but I'll do it for you and read my explanation before you demand an answer.
Step-by-step explanation:
When you look at a right angle, one forms 90°
A square has 4 sides, each should measure 90°.
That is how we know that point C measures 90°.
Now let's solve for x.
100+(x+10)+90°=90°
Solve the equation:
100+x+10+90=90
Step 1 : Solve for both sides.
100+x+10+90=90
(x)+(100+10+90)=90 ADD LIKE TERMS!
x+200=90
Step 2: Subtract 200 from both sides so you can make them equal.
x+200−200=90−200
x=−110
So, we get that <em>x=-110</em>. So <em>the blank side</em> should measure <em>90 degrees</em>.
Answer:
The perimeter of the regular octagon is 104 units
Step-by-step explanation:
we know that
The segment LM is the length of one side of the octagon
we have the coordinates
L(-6,-2) and M(6,3)
step 1
Find the distance LM
the formula to calculate the distance between two points is equal to

substitute the values




step 2
Find the perimeter
we know that
A regular octagon has eight equal sides
so
To find out the perimeter, multiply by 8 the length of the segment LM

The answer is D.
To get an area of any 4 sided object (like you text book) , we multiply the length and the width.
All the other answers don't multiply only 2 numbers together, so we know it must be D)
