Answer:
Step-by-step explanation:
Distribute the negative inside 2x+1
Remind that <u>negative</u><u> </u><u>multiply</u><u> </u><u>negative</u><u> </u><u>must</u><u> </u><u>equal</u><u> </u><u>positive</u><u>.</u>
variables cannot sum/add/subtract with constants.
They must be the same terms.
Therefore, our answer is 2x+6

Answer:
Step-by-step explanation:
By applying tangent rule in the given right triangle AOB,
tan(30°) =
By applying tangent rule in the given right triangle BOC,
tan(60°) =
OC = BO(√3)
OA + OC = AC
2√3(BO) = 60
BO = 10√3
OC = BO(√3)
OC = (10√3)(√3)
OC = 30
By applying tangent rule in right triangle DOC,
tan(60°) =
OD = OC(√3)
OD = 30√3
Since, BD = BO + OD
BD = 10√3 + 30√3
BD = 40√3
≈ 69.3

The radius goes from the center to the edge of the circle.
The diameter is twice as long as the radius; it is a segment going through the center with both endpoints on the circle
The circumference is the distance around the circle. Think of it as the perimeter of the circle.
