simplify 15(2/5+3x)

Solution

simplify

15 (\frac{2}{5} + 3 x)

45 x + 6

Solution steps

15 (\frac{2}{5} + 3 x)

Join

\frac{2}{5} + 3 x : \frac{15 x + 2}{5}

= 15 \cdot \frac{15 x + 2}{5}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{15 ( 15 x + 2 )}{5}

Divide the numbers:

\frac{15}{5} = 3

= 3 (15 x + 2)

Expand

3 (15 x + 2) : 45 x + 6

= 45 x + 6

\frac{4 ( sin ( 2 πn ) - πn cos ( 2 πn ) )}{n ^{2}}
