Answer:
3 non-congruent triangles
Step-by-step explanation:
Assume, side of cube is 1 unit.
24 triangles, faces of cube and side lengths = 1,1,√2
24 triangles, by 2 diagonal and one side and length = 1,√2
,√23
8 triangles, using bases of tetrahedrons of the cube and side lengths = √2
,√2
,√2
Therefore, 3 non-congruent triangles. are formed.
Answer:
D is correct option
Step-by-step explanation:
The correct option is D.
The standard quadratic equation is ax²+bx+c=0
Where a and b are coefficients and c is constant.
It means that constant are on the L.H.S and there is 0 on the right hand side.
Therefore to make it a quadratic equation first of all you have to add 11 at both sides so that the R.H.S becomes 0.
The given equation is:
2x2-x+ 2 = -11
If we add 11 on both sides the equation will be:
2x2-x+ 2 +11= -11+11
2x^2-x+13=0
Thus the correct option is D
You can further solve it by applying quadratic formula....
