What does the expression 2(21x + 75) represent

42x+150

Step-by-step explanation:

=(2)(21x+75)

=(2)(21x)+(2)(75)

Is there a story that goes with the question.

answer: what do you mean

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
