Question 2 of 5 Select the correct answer. What is the value of the eqpression when \( s=2 \) and \( t=-1.5 ? \) \[ -3\left|5-s^{3}\right|+3 t \] 135

complete the square \[ 2 x^{2}-10 x-20=8 \]

Find the square \( 2 x^{2}-10 x-20=8 \)

b) \( \frac{1}{2} \cdot\left(2-\frac{3}{2}-\frac{5}{6}\right)^{2} \)

\( \begin{array}{ll}\text { 2. } & 2 \cdot \mathrm{C}_{0}+3 \cdot \mathrm{C}_{1}+4 \cdot \mathrm{C}_{2}+\ldots+(\mathrm{n}+2) \cdot \mathrm{C}_{\mathrm{n}}=(\mathrm{n}+4) \cdot 2^{\mathrm{n}-1} \\ \text { 3. } & 2 \cdot \mathrm{C}_{0}+5 \cdot \mathrm{C}_{1}+8 \cdot \mathrm{C}_{2}+\ldots(\mathrm{n}+1) \text { terms }=(3 \mathrm{n}+4) \cdot 2^{\mathrm{n}-1} \\ \text { 4. } & 3 \cdot \mathrm{C}_{1}+7 \cdot \mathrm{C}_{2}+11 \cdot \mathrm{C}_{3}+\ldots \mathrm{n} \text { terms }=1+(2 \mathrm{n}-1) 2^{\mathrm{n}} \\ \text { 5. } & 7 \mathrm{C}_{1}-12 \cdot \mathrm{C}_{2}+\ldots(-1)^{\mathrm{n}-1} \cdot(5 \mathrm{n}+2) \mathrm{C}_{\mathrm{n}}=2\end{array} \)

Ex. (8): Find the new form of the equation of the curve Fig \( (7 \) \[ x^{2}+3 x y-y^{2}-x+5 y-6=0 \] When shifting axes at the point \( (-1,1) \) without change of direction. \[ (\alpha, \beta) \]
