1 answer:

5 0

$\bf 50=\pi 2(h+3)\implies 50=\stackrel{\textit{distributing first}}{2\pi h+6\pi }\implies 50-6\pi =2\pi h \\\\\\ \cfrac{50-6\pi }{2\pi }=h\implies 4.957747154594767 \approx h$

Answer:

Step-by-step explanation:

Hello, "the constant term has been written on the right side", it means that we add 18 to both sides to get.

$x^2+3x-18=0\\\\x^2+3x=18\\\\\text{We can see the beginning of } (x+\dfrac{3}{2})^2 \\\\x^2+3x=(x+\dfrac{3}{2})^2-\dfrac{3^3}{2^2}=18\\\\(x+\dfrac{3}{2})^2=18+\dfrac{9}{4}=\dfrac{18*4+9}{4}=\dfrac{81}{4}$
