Answer:
it has 11 faces 10 sides for the decagon + 1 for the base
It does have one face that is a decagon, which is the base, the rest are triangles
it has 20 edges
Step-by-step explanation:
X/2 + x/2 = 2x / 2 or just x. So x = 8/12 which can be simplified by their greatest common factor of 4. Divide both top and bottom by 4. This gives you x = 2/3.
Your answer for that equation is x = 2/3
Not sure what you mean by "decompose" though.
Answer:
m = 6
Step-by-step explanation:
4m + 2(8) = 5(8) (Given)
4m + 16 = 40 (Simplify)
4m + 16 - 16 = 40 - 16 (Subtraction Property of Equality)
4m = 24 (Simplify)
(Division Property of Equality)
m = 6 (Simplify)
Answer:
y = - x + 4
Step-by-step explanation:
gradient = change in y/change in x
1-6/3--2= -5/5 = -1
y= -x + c
1=-3+c
c=4
equation of line =
y= -x + 4
