step by step answer please​

Answer 1

Answer:

$\frac{12.5^3+7.5^3}{2.5^2+7.5^2-12.5\cdot \:7.5}=-76$

Step-by-step explanation:

$\frac{12.5^3+7.5^3}{2.5^2+7.5^2-12.5\cdot \:7.5}$

$=\frac{2375}{2.5^2+7.5^2-7.5\cdot \:12.5}$

$=\frac{2375}{-31.25}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{-b}=-\frac{a}{b}$

$=-\frac{2375}{31.25}$

$=-76$
