expand 1/5 (15+10x-5)

expand

\frac{1}{5} (15 + 10 x - 5)

2 x + 2

Solution steps

\frac{1}{5} (15 + 10 x - 5)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

\frac{1}{5} (15 + 10 x - 5) = \frac{1}{5} \cdot 15 + \frac{1}{5} \cdot 10 x + \frac{1}{5} (- 5)

= \frac{1}{5} \cdot 15 + \frac{1}{5} \cdot 10 x + \frac{1}{5} (- 5)

Simplify

\frac{1}{5} \cdot 15 + \frac{1}{5} \cdot 10 x + \frac{1}{5} (- 5) : 2 x + 2

= 2 x + 2

(y + \frac{b}{a}) \cdot (e^{a t} - \frac{b}{a})

g (\frac{m}{z} + \frac{n x}{l})

3 (x + \frac{1}{2})

2 (\frac{3 3}{2} + 3)
