since perimeter is the total of the length plus length plus width plus width:
L+L+W+W= 78 cm (given in the problem) as the total perimeter; and remember the length (we are told in the problem) is equal to 2 times width. so:
3 +2w+3+2w=78
6 +4w=78
6+4w-6=78-6
4w=72
w=18
<h2>
The required poynomial equation is .</h2>
Step-by-step explanation:
Given,
The zeros of the polynomial are - 4, - 2, 1 and 4
To find, the polynomial equation = ?
We know that,
The polynomial equation = (x - A)(x - B)(x - C)(x - D)
= (x + 4)(x + 2)(x - 1)(x - 4)
= [(x + 4)(x - 4)] [(x + 2)(x - 1)]
= ()()
= ()()
=
=
Thus, the required poynomial equation is .
Answer:
(1) 400
(2) 200
Step-by-step explanation:
Revenue (R) = ticket cost (C) * Number of sold (x)
R= Cx--------------------------------------------------------------- (1)
R = (C-0.75) * (x+100)
Cx = Cx +100C-0.75x -75
0.75x-100C = -75-------------------------------------------------(2)
R = (C+1.50)* (x-100)
Cx = Cx -100C+1.5x-150
-1.5x+100C= -150-------------------------------------------------(3)
Solving equations (2)and (3) simultaneously:
0.75x-100C = -75
-1.5x+100C= -150
-0.75x = -225
x= 300
(1) x+100
= 300 +100
= 400 people
(2) x-100
= 300-100
=200
