13.425

first you have to do whats in the parenthesis and then what ever answer you get you multiply it by whats outside of the parenthesis

$- 2.5 (3.7 - 9.07)$ $-2.5 (3.7 - 9.07)$

$\Rightarrow - 2.5 (- (9.07 - 3.7))$ $=> -2.5 (-(9.07-3.7))$

$\Rightarrow - 2.5 (- 5.37)$ $=> -2.5(-5.37)$ as $9.07 - 3.7 = 5.37$ $9.07 - 3.7 = 5.37$

$\Rightarrow - 2.5 \cdot - 5.37$ $=> -2.5 * - 5.37$ Removing the bracket

$\Rightarrow 2.5 \cdot 5.37$ $=> 2.5 * 5.37$ as $(-) \cdot (-) = +$ $(-) * (-) = +$

$\Rightarrow 13.425$ $=> 13.425$
