Which expression is equivalent to 2(x+3)

d

Step-by-step explanation:

multiply everything by 2.

2(x+3)

2·x = 2x

2·3 = 6

2x+6

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
