Find 4 consecutive odd numbers such that twice the sum of the least 2 numbers is 40 less than three times the sum of the greates
ANTONII [103]
4 consecutive odd numbers....x, x + 2, x + 4, x + 6

2(x + x + 2) = 3(x + 4 + x + 6) - 40
2(2x + 2) = 3(2x + 10) - 40
4x + 4 = 6x + 30 - 40
4x + 4 = 6x - 10
4x - 6x = -10 - 4
-2x = - 14
x = -14/-2
x = 7

x + 2 = 7 + 2 = 9
x + 4 = 7 + 4 = 11
x + 6 = 7 + 6 = 13

ur numbers are : 7,9,11,13 <==

The length of a rectangle is represented by x, the width is represented by 6x^2-4x-2. What is the area of the rectangle?
navik [9.2K]

Answer:

2x(3x^2-2x-1)

Step-by-step explanation:

Area of a rectangle is simply length times width

{6x^2-4x-2} * x    would be the area

That can be simplified to

6x^3-4x^2-2x

Which can be further simplified to

2x(3x^2-2x-1)
