16ax + 4x^2 +16a^2 HELP

Step-by-step explanation:

Assumed it is asking to factorize

Used formula:

m² +2mn + n² = (m + n)²

since both sides equal, there are infinitely many olutions.

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
