In the expansion of (3x^3 + 4x) (2x^2 5), what is the coefficient of x^3?

30x^5+40x^3

Step-by-step explanation:

I have a calculator so I put the whole thing in. This might not be much of a help and sorry there is no explanation for this question from me.

step-by-step explanation:

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
