Answer:
-12X-30
Step-by-step explanation:
No expressions were given, so it could be a different expression, but if you multiply out -6 to 2X and +5 then you end up with -12X-30 which is equivalent to -6(2X+5)
Answer:
157.1
Step-by-step explanation:
If you split the blue shape like in the picture, it shows that there is 1 large semicircle and 2 smaller ones.
The area of a semicircle is (pi×radius²)÷2
First, you would find out the area of the large semicircle by substituting in the numbers:
(3.142×10²)÷2=157.1
Then you would find out the area of the smaller semicircle:
The diameter of the semicircle is 10 so to find the radius you would half it.
(3.142×5²)÷2=39.275
To find the area of the whole shape, you would have to take away 39.275 and then add it back on so the answer would be 157.1
Hope this helps :)
Assuming those are all the lengths of the shape you need to take the sum of all the lengths to get the perimeter.
2+5+5+2=14m is the perimeter
The second option is the answer
