simplify 10(2/5-2y)

Solution

simplify

10 (\frac{2}{5} - 2 y)

- 20 y + 4

Solution steps

10 (\frac{2}{5} - 2 y)

Join

\frac{2}{5} - 2 y : \frac{- 10 y + 2}{5}

= 10 \cdot \frac{- 10 y + 2}{5}

Apply the fraction rule:

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

= \frac{10 ( - 10 y + 2 )}{5}

Divide the numbers:

\frac{10}{5} = 2

= 2 (- 10 y + 2)

Expand

2 (- 10 y + 2) : - 20 y + 4

= - 20 y + 4

\frac{8 ( 2 ( - 1 ) ^{n} - π ^{2} ( - 1 ) ^{n} n ^{2} - 2 )}{π n ^{3}}

\frac{1}{\frac{16 x ^{2}}{n ^{2}} - \frac{8 x}{n} + 1}

\frac{37.68}{3}

\frac{20 ( 110 - 12010 )}{3}

2 x - 4 cos (x^{2} + 3 x) (2 x + 3)
