Answer:
arc DB length = 14π feet
Step-by-step explanation:
Assuming point A is the center of the circle, arc DC has measure 180°. Arc DB has measure 40° less, so is 140°. Since you want this in terms of π, we need to convert the degree measure to radians. We do that by multiplying by (π/180) radians per degree:
arc DB = 140° = 140°(π/180°) radians
__
Now that we know the arc measure in radians, we can find the length of the arc. It is given by the formula ...
s = rθ
where r represents the radius and θ is the measure of the arc in radians.
The arc length is ...
s = (18 ft)(7π/9) = 14π ft
Arc DB has a length of 14π feet.

In this problem, you are asked to translate this verbal expression into algebraic expression. Then you must simply this expression if possible.So for this problem, the algebraic expression is:
1.2 ( w + u / 12) -> so simplifying this, will give us:
= 1.2w + 1.2*u/12
= 1.2w + u/10 would be the answer.
