Answer:
9 : 1
Step-by-step explanation:
given a linear ratio = a : b, then the corresponding area ratio is
a² : b²
Here the linear ratio of their edges = 3 : 1, hence
ratio of surface areas = 3² : 1² = 9 : 1
Answer:
The factors of 
is ((x+y)-5)(2x+2y+1)
Step-by-step explanation:
Given polynomial
=>
To Find:
The factors of the polynomial =?
Solution:
Lets assume k = (x+y)
Then can be written as 
Now by using quadratic formula
k =
where
a= 2
b= -9
c= -5
Substituting the values, we get
k =
k =
k =
k =
k =
k= 
k = 
k = 
Solving the RHS we get
Substituting k = x+y

Answer:
(x+3)^2 + (y-4)^2 = 64
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k)^2 = r^2 where ( h-k) is the center and r is the radius
(x--3)^2 + (y-4)^2 = 8^2
(x+3)^2 + (y-4)^2 = 64
