$- 10 - 90 x$

Explanation:

Given,

$\left(1 + 9 x\right) \times - 10$

The expression can be rewritten as,

$= - 10 \left(1 + 9 x\right)$

Multiply $- 10$ by each term within the brackets.

$= - 10 \left(1\right) - 10 \left(9 x\right)$

$= \textcolor{g r e e n}{| \overline{\underline{\textcolor{w h i t e}{\frac{a}{a}} \textcolor{b l a c k}{- 10 - 90 x} \textcolor{w h i t e}{\frac{a}{a}} |}}}$
