1 answer:

4 0

1. $\mathrm{Group\:like\:terms} \ \textgreater \ 24h-10h+3d+8d$

$\mathrm{Add\:similar\:elements:}\:24h-10h=14h \ \textgreater \ 14h+3d+8d$

$\mathrm{Add\:similar\:elements:}\:3d+8d=11d \ \textgreater \ 14h+11d$

2. $\mathrm{Group\:like\:terms} \ \textgreater \ 12s+4s-2+4$

$\mathrm{Add\:similar\:elements:}\:12s+4s=16s \ \textgreater \ 16s-2+4$

$\mathrm{Add/Subtract\:the\:numbers:}\:-2+4=2 \ \textgreater \ 16s+2$

Hope this helps!

Answer:

Please see the attached picture for the full solution.

*From the 4th line of the 1st image, you could also expand it using

(a +b)²= a² +2ab +b² and

(a -b)²= a² -2ab +b².

When squaring a fraction, square both the denominator and numerator.

➣(a/b)²= a²/b²
