area=legnth times width
therefor
width=area/legnth and
legnth=area/width

Answer:

9. First Five terms

If n=0. Then,

\frac{4(0) - 5}{2}

\frac{0 - 5}{2}  =  \frac{ - 5}{2}

If n=1. Then,

\frac{4(1) - 5}{2}

\frac{4 - 5}{2}  =  \frac{ - 1}{2}

If n=2. Then,

\frac{4(2) - 5}{2}

\frac{8 - 5}{2}  =  \frac{3}{2}

If n=3. Then,

\frac{4(3) - 5}{2}

\frac{12 - 5}{2}  =  \frac{7}{2}

If n=4. Then,

\frac{4(4) - 5}{2}

\frac{16 - 5}{2}  =  \frac{11}{2}

If n=5. Then,

\frac{4(5) - 5}{2}

\frac{20 - 5}{2}  =  \frac{15}{2}

If n=6. Then,

\frac{4(6) - 5}{2}

\frac{24 - 5}{2}  =  \frac{19}{2}

Solve the equation by completing the square. Round to the nearest hundredth if necessary. x^2 + 2x = 17
earnstyle [38]

Answer:

<h2>x = -5.24 or x = 3.24</h2>

Step-by-step explanation:

(a+b)^2=a^2+2ab+b^2\qquad(8)\\\\x^2+2x=17\\\\x^2+(2)(x)(1)=17\qquad\text{add}\ 1^2\ \text{to both sides}\\\\\underbrace{x^2+(2)(x)(1)+1^2}_{(*)}=17+1^2\\\\(x+1)^2=18\iff x+1=\pm\sqrt{18}\qquad\text{subtract 1 from both sides}\\\\x=-1\pm\sqrt{18}\\\\x\approx-1-4.24=-5.24\ \vee\ x\approx-1+4.24=3.24
