There are 2 short sides x and 1 long side y.
x+x+y=1,800
2x+y=1,800
y=1,800-2x
The area of the rectangle is A=x(1,800-x).
A is a function with variable x. Moreover it is a quadratic (second degree) function.
The graph of the function is a parabola which opens downwards, because the signs of the leading coefficients of the factors, multiply to minus:
(x)(-x)=-x^2.
This means that the highest point of the parabola, is its vertex V(h,k), so the function takes its largest value for x=h.
The roots of A=x(1,800-x) are x=0 and x=1,800, thus the x coordinate of the vertex, must be the midpoint of 0 and 1,800, that is 900.
Answer:
A=x(1,800-x)
largest area is when x=900
The probability would be 50%. The way to find this answer is to add up the total number of songs then divide 50(the total of rock songs) by the sum of the numbers which is 100, and 50/100 is equal to 0.50 and if you multiple by 100 that will give u the percentage(or just look at the first 2 decimal places)
1. 4 3/8= 35/8
2. the digit that makes 3,42_ divisible by 9 is 0
3. 39/9 = 4 3/9 = 4 1/3

Answer:
5 and -5
Step-by-step explanation:
Opposite numbers are the same distance from 0 on the number line. So, each of the numbers is a distance from zero that is half the distance between them.
The numbers are 10/2 = 5, and -5.
