Answer:
The option 
is correct
The difference of the given expression is
Step-by-step explanation:
Given expression is 
To find the difference of the given expression as below :
( using the formula 
)
(adding the like terms)
( by factoring the quadratic polynomial )
Therefore
Therefore the difference of the given expression is
Therefore option is correct
Exponential Decay because it’s decaying by .5 which is smaller than 1
Lets use proportion
let the perimeter of the smaller figure be 'x'
8:18::x:24
Product of means=product of extreames
24 x 8= 18 x 'x'
192=18x
x=10.6666667 units
Ans: the perimeter of the smaller figure is 10.6666667 units
X2 + y2 - 14x + 10y = 250
x2 -14x + 49 - 49 + y2 + 10x + 25 - 25 = 250
(x - 7)^2 - 49 + (y+5)^2 - 25 = 250
(x-7)^2 + (y+5)^2 = 250 + 49 + 25
(x-7)^2 + (y+5)^2 = 324
Therefore the radius, r
r = 324^0.5
r = 18
18.75 because all sides of a square are equal so 75/4=18.75
