X = 7 . You have to subtract the total from the amount your adding, then divide the 6. then you get your answer
The area of CEF will be calculated as follows:
The ratio of (BE+FD):EF is:
3:2
But the area of BDC=1/2ABCD
thus
BDC=1/2*100=50 in
hence the area of CEF will be:
(fraction of CEF)×(Area of BDC)
fraction of CEF=2/5
hence the area will be:
2/5×50
=20 in²
-1/2(-3/2x + 6x + 1) - 3
Simplify.
(3/4x - 3x - 1/2) - 3
Get rid of the parenthesis.
3/4x - 3x - 1/2 - 3
Add like terms.
(3/4x - 3x) + (-1/2 - 3)
Simplify.
-2 1/4x + (-3 1/2)
Get rid of the parenthesis.
-2 1/4x - 3 1/2
Hope I helped! :)
Answer:
as two semicircles and a rectangle
Step-by-step explanation:
If you extend the radii shown, each becomes an end of the rectangle, and also a boundary for a semicircle. The result is two semicircles and a rectangle.
_____
Of course, two semicircles make a circle, so you could also decompose this to a circle and a rectangle.
<span>To start, look at the factors of the smallest number: in this case, 50. The factors of 50 are: 1,2,5,10,25,50. Moving to the next smallest number, 125, the factors are: 1,5,25,125. The final number, 275, has factors of: 1,5,11,25,55,275. Looking at all three of these numbers, the common factors are: 1,5,25. The greatest common factor, then, is 25.</span>
