The answer is 8n^2
2x2 is 4 x 2 is 8 two n variables so multiple it by 2 and you get your answer

Answer:
C.E=18 cm
Step-by-step explanation:
we know that
If the circle O is inscribed in triangle ABC
then
A.F=A.D=6 cm
B.D=B.E=14 cm
C.F=C.E=?
The perimeter of triangle is equal to
P=2(6)+2(14)+2(C.E)
P=76 cm
so
76=2(6)+2(14)+2(C.E) -----> solve for C.E
76=12+28+2C.E
2C.E=76-40
C.E=36/2
C.E=18 cm

Answer:
x = 4
Step-by-step explanation:
From the pythagoras theorem
(x+2)^2 = x(5+x)
x^2 + 4x + 4 = 5x + x^2
x^2 + 4x + 4 - 5x - x^2 = 0
-x + 4 = 0
4 = x
