The greatest common factor is 4, so divide both numbers by 4 and you'll have it
56/4=14
20/4=5
the answer is 14/5
Answer:
x = - 
Step-by-step explanation:
Multiply through by 4 to clear the fraction
15 - 28x = 36 ( subtract 15 from both sides )
- 28x = 21 ( divide both sides by - 28 )
x = 
= -

(A) One circle : four triangles
Example:
If there is two circles, the triangles will double like it shows [evidences]
Answer:
D. 22.5 sq. un.
Step-by-step explanation:
W divides BU so that there is a ratio of 1;2 meaning that there are 3 parts.
That means that 3 parts is BUV; we know that one of those parts is 4.5 sq. un. so 4.5*3=13.5 sq. un. - Also 4.5*2=9 to get WUV
V is the midpoint of the line BS so that means that BUV and UVS are equal
we know that BUV is 13.5 so we multiply that by 2 to get the whole triangle
=27
The last step is to get rid of BVW which we know is 4.5
27-4.5=22.5
