expand 2pi(k+k/5)

Solution

expand

2 π (k + \frac{k}{5})

Solution

2 πk + \frac{2 πk}{5}

Solution steps

2 π (k + \frac{k}{5})

Apply the distributive law:

a (b + c) = ab + a c

a = 2 π, b = k, c = \frac{k}{5}

= 2 πk + 2 π \frac{k}{5}

Multiply

2 π \frac{k}{5} : \frac{2 πk}{5}

= 2 πk + \frac{2 πk}{5}
