Ответ:
the complete question in the attached figure
step 1
Find the distance of the center of the wall from the left end of the wall
distance=(1/2)*24--------> 12 ft
so
If x is the distance from a painting edge to its corresponding end of the wall, then
|x-12| is the distance from the painting edge to the center of the wall
and
If the painting is centered, then 2|x-12| represents the width of the painting
Since the painting is 10 ft wide,
we have 2|x-12|=10
therefore
the answer is the option B
2|x-12|=10
Ответ:
f(n) = f(n - 1) - 5
f(1) = 2
f(2) = f(2 - 1) - 5 = 2 - 5 = -3
f(3) = f(3 - 1) - 5 = f(2) - 5 = -3 - 5 = -8
f(4) = f(4 - 1) - 5 = f(3) - 5 = -8 - 5 = -13
f(5) = f(5 - 1) - 5 = f(4) - 5 = -13 - 5 = -18
f(6) = f(6 - 1) - 5 = f(5) - 5 = -18 - 5 = -23
