Answer:
7920
Step-by-step explanation:
you can use the binomial theorem obviously but you can also use symbolabs or wolframalpha and just solve it like that.
a.
Let
5x = number of games won
2x = number of games lost
The total number of win and lose is 154. So
5x + 2x = 154
Solving for x,
7x = 154
x = 22
Therefore, the number of games won is 5*22=110 and the number of games lost is 2*22 is 44.
b.
Let
6x = first side of the triangle
7x = second side of the triangle
9x = third side of the triangle
The perimeter of a triangle is the total of all sides. So,
6x + 7x + 9x = 88
22x = 88
x = 4
Therefore, the three lengths of the side are 6*4=24, 7*4=28, and 9*4 = 36

Answer:
-71i + 12j +47k
Step-by-step explanation:
The notation of the distance moved
In x-direction = -71
Considering the left side as the positive y- direction;
In y-direction= 12
In z-direction = 47
Therefore, the vector notation is
Displacement r = -71i + 12j + 47k
