Answer:
39 feet.
Step-by-step explanation:
E use the Pythagoras theorem:
40^2 = 8^2 + h^2 as h is the height we require.
h^2 = 1600 - 64
h^2 = 1536
h = 39.19 feet
umm km / nk
I DONT know if this is right...…can u plz mark me brainiest? I really need it!!!!
(x-2) (x+2)
------------------
f(-2) = -1
-2 is x, so replace x as -2 into the equation
f (-2) = 2(-2) + 3
f (-2) = -4 + 3
f (-2) = -1
C2 + a2 +2 = b
Would be the new formula
