Answer is 7/12 I know it is because, well I just know it is
The length of the dollhouse room is 156. Because you take the 1248 and divide by the 8. Which then gives you 156. To verify this answer, you would multiply 156 by 8 and you should get the answer 1248. so the length of the room is 156.
Remember, you can do anything to an equation as long as you do it to both sides
we hate fractions so times both sides by 4
4A+8x-7x=8x+24a+8
combine like terms
4A+x=8x+24a+8
minus x both sides
4A=7x+24a+8
minus (24a+8) from both sides
4A-24a-8=7x
divide both sides by 7
Answer:
Area = πr²
Circumference = 2πr
Step-by-step explanation:
When given the radius r ,
Area of a circle A = πr²
Circumference of the circle C = 2πr
When given diameter d,
Area of a circle A = πd²/4
Circumference of a circle = πd
To find the radius r and d from area A,
r = sqrt(A/π)
d = sqrt(4A/π)
To find the radius r and diameter d from a given circumference C,
r = C/(2π)
d = C/π
Where d = 2r
Well not all lines are lines of symmerty, because if you draw a let's say a rectangle on a piece of paper and draw a diagonal line through it, well the two sides don't really lie perfectly on one another!!
