Answer:
9t^3 +t^2
Step-by-step explanation:
The perimeter of the figure is the sum of the lengths of the sides. The side lengths are represented by the polynomials shown, so the perimeter (P) is their sum:
P = (4t^3 -5) + (4t^3 -5) + (t^2 +9) + (t^3 -t^2 -11) + (t^2 +12)
Rearranging to group like terms:
P = (4t^3 +4t^3 +t^3) + (t^2 -t^2 +t^2) + (-5 -5 +9 -11 +12)
P = 9t^3 +t^2
The perimeter of the figure is represented by the polynomial 9t^3 +t^2.

Complete Question
Stillwater Junior High divides students into teams taught by a group of teachers. The table shows the number of students in each team.
Team{Number of Students}
Acers{78}
Blazers{80}
Outbacks{83}
Quasars{77}
Voyagers{82}
<u>Total-400</u>
Answer:
(A)81/399
Step-by-step explanation:
The probability that the Principal selects a voyager on the first try is:
82/400
Since another student is to be selected, the <u>total population has reduced by 1 </u>and the <u>number of voyagers likewise has been reduced by 1.</u>
Therefore:
Probability that another voyager is selected on the second try =
81/399
<u>The correct option is A.</u>

Answer:
Step-by-step explanation:
According to the diagram MK is the angle bisector of ∠LMJ in the triangle LMJ.
Use angle bisector theorem, which states:
- <em>an angle bisector of an angle of a triangle divides the opposite side into two parts that are proportional to the other two sides of the triangle.</em>
<em />
Applied to the given triangle, the ratios are:
Use segment addition postulate and substitute known values to get:
- (LJ - JK)/JK = LM/JM
- (14 - JK)/JK = 50/48
- 50JK = 48(14 - JK)
- 50JK = 672 - 48JK
- 50JK + 48JK = 672
- 98JK = 672
- JK = 672/98
- JK = 6.86 (rounded)
