Answer:
5 edges and 4 vertices
Step-by-step explanation:
Answer:-4
Step-by-step explanation:
1.x^2 +6x - 4 = 6x
X^2 + 6x -4 - 6x = 0
X^2 - 4 = 0
By difference of two squares :
X^2 - 4 = 0 can be written as (x-2) (x+2) = 0
(X-2)=0 therefore x= 2
(X+2)=0 therefore x= -2
2. X^2 - 8x = -6x
X^2 -8x + 6x = 0
X^2 - 2x = 0
X(X-2) = 0
X= 0, X= 2
I is the right one because it is a half and they both look the same
So first you find 10% which is 34.5
Then you multiply 10% by 4 to get 40% which is = 138
