Answer:
its B. y=2(x+7/2)^2+1/2 :)
Step-by-step explanation:
Answer:
πr^2 + L×W
Step-by-step explanation:
we have to find the two areas then we add to get the total area.
We are already given with the following
BC = 4.5
CD = 7.7
AD = 16.7
We are asked for AB
Assuming that the line segments are colinear, we have the equation
AB + BC + CD = AD
Substituting
AB + 4.5 + 7.7 = 16.7
AB = 4.5
The answer is 184. 2711
Round it off is 184
Hope that helped :D

- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cosθ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
Angle θ = 28°
Adjacent Leg = EF = <em>x</em>
Hypotenuse = DF = 18
<u>Step 2: Solve for </u><em><u>x</u></em>
