Two less than three times the width of a rectangle is equal to the lenght.The area of the rectangle is 65 square ft.What is the
lenght of the rectangle
1 answer:
Answer:
length: 13 feet
Step-by-step explanation:
width: x
length: 3x - 2
Area = Length * Width
65 = x(3x - 2)
65 = 3x² - 2x
3x² - 2x - 65 = 0
(3x + 13)( x - 5) = 0
3x + 13 = 0 and x - 5 = 0
3x = -13 x = 5
x = - 13/3
**Width cannot be a negative number so we'll discard -13/3.
width: x = 5
length: 3x - 2 = 3(5) - 2 = 13

What figure is the problem talking about?
12x^3 +2x^2-30x = 8
2x( 6x^2 +x -15) = 8
so 2x= 8, x=4
(2x) ( 2x-3) ( 3x+5) = 8
2x-3 = 8
2x= 11
x= 5.5
3x+5=8
3x= 3
x=1
