Three consecutive odd numbers add up to 147. Write these three odd numbers in ascending order (smallest to largest).

Solve  \(2x – 5 = 4x + 9\).

Solve  \(\dfrac{1}{5} = \dfrac{4}{{3x + 2}}\).

Expand and simplify \({\left( {x + \dfrac{1}{x}} \right)^2}\).

Find \(A \), if \(\dfrac{9}{{\left( {x – 1} \right)\left( {3x – 7} \right)}} \div \dfrac{{x + 3}}{{x – 1}} = \dfrac{A}{{\left( {3x – 7} \right)\left( {x + 3} \right)}}\).

If  \(a = – 2,b = 3\)  and  \(c = 9\),   find the value of  \({\left( {a + b} \right)^2} + \sqrt {4c} \).

Find  \(b\),   given  \(A = \dfrac{{a + b}}{{ab}} \)  where  \(A = 22\)  and  \(a = 11\),   correcting to two significant figures in ascending order.

Expand and simplify \(- 5\left( {4{x^2} + 3} \right)\left( {4{x^2} – 3} \right)\).

A sequence is defined by \({u_n} = {3^n}\). Find \({u_4}\).

Find the interest rate per annum, correcting to 2 decimal places, that would enable an investment of \($5000\) to grow to \($7000\) over 3 years if interest is compounded quarterly.
