4 consecutive odd integers....x , x + 2, x + 4, x + 6
product of 2 smaller numbers is 64 less then the product of the 2 larger numbers....
x(x + 2) = (x + 4)(x + 6) - 64
x^2 + 2x = (x^2 + 10x + 24 - 64)
x^2 + 2x = x^2 + 10x - 40
2x = 10x - 40
2x - 10x = -40
-8x = -40
x = -40/-8
x = 5
x + 2 = 5 + 2 = 7
x + 4 = 5 + 4 = 9
x + 6 = 5 + 6 = 11
ur numbers are : 5,7,9,and 11

Answer:
8 cm
Step-by-step explanation:
... BO/OD = AO/OC = 3/1
Written another way, this is ...
... OD : BO = 1 : 3
Now, BD = OD + BO, so we have
... BD : BO = (OD +BO) : BO = (1 +3) : 3 = 4 : 3
That is, BD = 4/3 × BO
... BD = 4/3 × 6 cm = 8 cm
Actually Welcome to the concept of areas,
we know that, area of rectangle = length * width,
here, length = x-2 and width = x-1
hence, area = (x-2) (x-1)
==> area = x^2 -x -2x +2
==> Area = x^2 - 3x + 2
hence the Option D.) is correct
Hi,
