Answer: 7.4a+b

1. distribute

=5a+(2.4)(a)+(2.4)(0.5b)+−0.2b

=5a+2.4a+1.2b+−0.2b

2. combine like terms

=5a+2.4a+1.2b+−0.2b

=(5a+2.4a)+(1.2b+−0.2b)

=7.4a+b

\\ \sf\longmapsto \dfrac{1-cos2A}{1-sin2A}

<h3>LHS</h3>

\boxed{\sf \dfrac{cosA}{sinA}=cotA}

\\ \sf\longmapsto \dfrac{1-cos2A}{1-sin2A}

\\ \sf\longmapsto 1-cot2A

\\ \sf\longmapsto 1-\dfrac{1}{tan2A}

\\ \sf\longmapsto \dfrac{tan2A-1}{tan2A}

\\ \sf\longmapsto tan2A
