Answer:
x = -5 ; y= -1
Step-by-step explanation:
10y = -10
y = -1
-8x = 44 -4
-8x = 40
x = -5
Answer:
C
Step-by-step explanation:
First, factor the original expression:
As we can see, D is the same as above. Eliminate D.
Go through each of the answer choices.
A:
This is equivalent to what we factored. Eliminate A.
B:
This is again equivalent to what we factored. Eliminate B.
C:
This cannot be simplified and it is not equivalent to what we have previously. C is not the equivalent expression.
Hey user!
your answer is here..
we know about EULER'S FORMULA, it is a formula used to verify a polyhedron or to calculate the number of faces, vertices or edges.
Euler's formula = F + V - E = 2
given :-
faces = 28, verticies = 50 and edge = ?
we know that F + V - E = 2
therefore 28 + 40 - E = 2
==> 68 - E = 2
==> - E = 2 - 68
==> - E = - 66
==> E = 66
hence, the number of edges of the polyhedron is 66.
cheers!!
