You are given a rectangle and are told that the length is 1 cm more than twice the width of the rectangle. The area of the rect. is also given, and is 21 cm^2.
Find the length and width. To do this, represent the length by y and the width by x. Then "1 cm more than twice the width" comes out to y=2x+1 (cm).
Since the area of a rect. is equal to the product of its length and width,
x(2x+1)=21 cm^2. Multiply out x(2x+1). show your work. Next, subtract 21 from both sides. Write your algebraic expression on the left side as a quadratic equation in standard form.
Solve this quadratic equation for x. Recall that x (in cm) will represent the width of the rect., and y=2x+1 (in cm) will repr. the length.
The answer to this question could be 44
So what you want to do is draw a circle, then draw one straight across the middle and then one straight top to bottom! :)
From the information given by the graph
Year 1 visitors
June = 9450
July = 9500
August = 9600
Year 2 visitors
June = 9450
July = 9600
August = 9800
Total visitor Year 1 = 9450 + 9500 + 9600 = 28550
Total visitor Year 2 = 9450 + 9600 + 9800 = 28850
Visitor in Year 2 is 28850-28550 = 300 more than visitor in Year 1
4(1+1+2)-2(1)+8+4 you would just plug it in for x and y. And then solve the equation.
