h(4) = 1/2 (4) - 8 = 2 - 8 = -6
Step-by-step explanation:
Andrew can reach a maximum of
high up the wall.
The right-angled triangle formed can be solved using the
ratio. that is

where
is the distance from the foot of the wall to the tip of the ladder where it rests on the wall. Substituting, and solving for
, we get

Since Andrew can reach an extra
above the point where the ladder rests against the wall, the maximum height Andrew can paint is

Answer:
A
Step-by-step explanation:
if you subtract 54 from 180 you would get 126
So it would be in six years because if you do it, it would be
garden 1: 2,4,6,8
garden 2: 3,6,9
and the lowest common multiple is 6 so in 6 years is when it will happen again
