Select the expression that is NOT equivalent to 2 × (3 + 6). A. 6 + 12

B. (2 × 3) + (2 × 6)

C. (2 × 6) + (2 × 3)

D. (2 × 3) + (3 × 6)

D

Step-by-step explanation:

in answer D, the values would equal "6" and "18" which is not equivalent to the given equation

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
