Step-by-step explanation:
f°g=
if the denominator is zero the number is undefined which makes it not in the domain of the function
set 
equal to 0
the values for x is 0 or 6
so the only value that is not in the domain of f°g is 0 and 6
Hope that helps :)
L=7+w
P=(12x+14)=2(6x+7)
l+w= P/2 = 2(6x+7)/2= 6x+7
l+w=6x+7
2l = 6x+7
l = (6x+7)/2
l=7+w
-> w= l-7
= [(6x+7)/2] -7
= (6x+7-14)/2
= (6x-7)/2
Hi,
Divide using Copy Dot Flop,
2/3 ÷ 4/5 = 2/3 x 5/4
Multiply,
2 x 5 = 10
3 x 4 = 12
= 10/12
Simplify,
10/12 = 5/6
Answer - 5/6
Well idk what the numbers are, but the formula to find the are is 3.14(pi) x r^2
