Answer:
??????????
Step-by-step explanation:
Since we know that <C is congruent to <E, we can say that: A. the two triangles are similar by SAS.
<h3>The properties of similar triangles.</h3>
In Geometry, two triangles are similar when the ratio of their corresponding sides are equal in magnitude and their corresponding angles are congruent.
Ratio = BC/AC = 6/3 = 2.
Ratio = FE/DE = 4/2 = 2.
Thus, the ratio of their corresponding sides are equal in magnitude i.e BC/AC ≡ FE/DE.
Since we know that <C is congruent to <E, we can say that the two triangles are similar by side, angle, side (SAS) criterion.

Y=-x^2-2
dy/dx=-2x and d2y/dx2=-2
Since acceleration is a negative constant, when the velocity equals zero, it will be an absolute maximum for y(x)
dy/dx=0 when -2x=0, x=0
y(0)=-2
So the vertex is at the absolute maximum, which is the point (0,-2)
I don't understand, but, two form a triangle your two SHORTEST sides have to equal LARGER than your LONGEST side. Example: 2,3,4
The two shortest sides are 2 and 3. 2+3=5 Is the sum greater than the largest side,4,? Yes, therefore it makes a triangle.
Answer:
6n +7
Step-by-step explanation:
You cannot solve since this is an expression, you can only simplify
-2(-3-3n)+1
Distribute the -2
-2*-3 -2*-3n +1
6 +6n +1
Combine like terms
6n +7
