Step-by-step explanation:
Please find the image file of the graph.
We know so because the triangle is isosceles.
when
is called by
.
We know that since E and D are tangent points to a circle.
They have since D and F are tangent points only to circle.
Thus, if the perimeter is 32, the following is the result:
Therefore the length of

Answer:
A
Step-by-step explanation:
We have the expression:
And we want to find its sign given that a>0 and b<0.
Notice that the expression is already negative since we have -4.
a>0 means that a is positive. Therefore, we can ignore it since it won’t do anything.
b<0 means that b is negative. Therefore, we will have two negatives being multiplied together. Hence, this will make a positive.
Therefore, the sign of our expression will be positive.
We can see this with an example. Let a=1 (1>0) and let b=-1 (-1<0). Then:
So, the sign is positive.
Hence, the answer is A.
