Required
Select the true statements
First, is a statement about the area.
The area is calculated as:

So, we have:

(a) is true
Next, is a statement about the circumference.
This is calculated as:

So, we have:

(e) is true
Answer:
positive linear is correct answer
Answer:
16 and 4
Step-by-step explanation:
Let (x+y) =20 and (x-y)=12 then:
Isolate for x in each equation
x=20-y and x=12+y
Set the equations to equal each other since the value of x should be the same for both
20-y = 12+y
Rearrange so that y is on one side and the numbers are on the other
8 = 2y
y= 8/2
y= 4
Now substitute the y- value back into either of the original equations
x+y= 20
x+4 = 20
Rearrange and isolate x
x = 20-4
x = 16
So the two values are 16 and 4
You haven't included enough information for the question, but assuming that a and b are the same then a is 4 and b is 4
Answer:
Your answer is x = 24 , y =8√3
