Answer: a = 3.6

<u>Step-by-step explanation:</u>

$\dfrac{2}{3}(6a+9)=20.4\\\\\\\text{Distribute the }\dfrac{2}{3}\ \text{by multiplying it by each term in the parenthesis:}\\\dfrac{2}{3}(6a)+\dfrac{2}{3}(9)=20.4\\\\\\\text{Cancel out common terms then Multiply:}\\2(2a)+2(3)=20.4\\4a+6=20.4\\\\\text{Subtract 6 from both sides:}\\4a=14.4\\\\\text{Divide both sides by 4:}\\a=3.6$

$\bf \left( \cfrac{1}{2} \right)^3\implies \left( \cfrac{1}{2} \right)\left( \cfrac{1}{2} \right)\left( \cfrac{1}{2} \right)\implies \cfrac{1}{2}\times \cfrac{1}{2}\times \cfrac{1}{2}$
