Answer:
Step-by-step explanation:
Return Of Investment: <u><em>The performance used to evaluate the efficiency of an investment or compare the efficiency of a number of different investments. </em></u>
<u><em></em></u>
It is a performance level used to compare the efficiency of one investment or more to several or just one more investments. They also evaluate the efficiency of one investment.
Return Of Investment (ROI) is very popular because it is simple, skilled and resourceful. If an investments ROI is net is positive, this tells them that it is worthwhile and has some use to it. If it is low, it lets people know that this is probably not the best solutions, and to not waste their time on something that won't work anyway.
Answer:
9)
-
⊥
---------Given
- ∠
and ∠
are right angles----------------definition of perpendicular lines
10)
- PT bisects AY-----------------------------Given
- AR≅RY---------------------------------------definition of segment bisector
11)
- OS bisects ∠CSW--------------------given
- ∠CSO≅∠WSO-------------------------definition of angle bisector
Step-by-step explanation:
9) Given, ⊥
⇒∠ and ∠ are right angles (definition of perpendicular lines)
10) Given, 
bisects 
⇒
≅
(definition of segment bisector)
11) Given, 
bisects ∠
⇒∠
≅∠
(definition of angle bisector)
For the answer to the question above,
We can see that, DP = PC, AD = BC and ∠ ADP = ∠ BCP = 30° ( SAS postulate )
So the answer to the question above is the last one among the given choices which is <span>Triangles APD and BPC are congruent SAS postulate.

Answer:
x=62; scalene triangle
Step-by-step explanation:
There are 180° in a triangle and a straight angle.
You start by subtracting 180-127 to get the angle opposite to the 127 degree angle. This is 53 degrees. Then you subtract the total amount of degrees by adding the two known angles 65+53 and subtracting them by 180. You do this to find the last angle. 180-118=62. x=62°
All of the angles are different so it is a scalene triangle.
because ( (-2)³+8))/(-2+2)=0/0,
you use formula a³+b³°(a+b)(a²-ab+b²).
therefore (x³+8)/(x+2) = ( (x+2)(x²-2x+4))/(x+2) = x²-2x+4
so lim x->-2 (x²-2x+4) = (-2)²-2*(-2)+4=
=4+4+4=12.
