Answer: the length of the shortest side is 15ft.
the length of the shorter or third side is 18ft
the length of the longest side is 26ft
Step-by-step explanation:
Let x represent the length of the shortest side of the triangular section.
Let y represent the length of the third or shorter side of the triangular section.
Let z represent the length of the longest side of the triangular section.
The perimeter of the triangular section is 59 ft. It means that
x + y + z = 59 - - - - - - - - - -1
the longest side of a triangular section is 4 ft shorter than twice the shorter side. It means that
z = 2x - 4
the third side is 3 feet longer than the shortest side. It means that
y = x + 3
Substituting z = 2x - 4 and y = x + 3 into equation 1, it becomes
x + x + 3 + 2x - 4 = 59
4x - 1 = 59
4x = 59 + 1 = 60
x = 60/4 = 15ft
y = x + 3 = 15 + 3
y = 18 ft
z = 2x - 4 = 2 × 15 - 4
z = 26

Step-by-step explanation:
Answer: Cola is more profitable over Coffee
Step-by-step explanation:
E(cola) = 0.3 * 1500 + 0.7 * 5000
E(cola) = 450 + 3500
E(cola) = 3950
E(coffee) = 0.3 * 4000 + 0.7 * 1000
E(coffee) = 1200 + 700
E(coffee) = 1900
From the decision tree which is attached, and the calculations above, it would be advised that the firm should focus on Cola, since it has a higher expected revenue of $3950, compared to the expected revenue of $1900 for coffee.

Answer:
I guess that the equations are:
P*P = Q*6
and
Q - P = 3
now, in the second equation we have:
Q = 3 + P
we can replace it in the first equation:
P^2 = (3 + P)*6 = 6P + 18
then we have the quadratic equation:
P^2 -6P - 18 = 0
Now, we can find the solutions of these equations are:
then the solutions are:
P = (6 + 10.4)/2 = 8.2
and
P = (6 - |0.4)/2 = -2.2
Then, if P = 8.2, then we must have Q = 11.2
and if P = -2.2, then Q = 0.8
If ur talking abt symmetry then uh
that figure most definitely doesn’t have a line of symmetry
