7)<br> Find the distance between the points B(-2, 14) and C(3, 8) to the nearest tenth.

RoseWind [281]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ B(\stackrel{x_1}{-2}~,~\stackrel{y_1}{14})\qquad C(\stackrel{x_2}{3}~,~\stackrel{y_2}{8})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ BC=\sqrt{[3-(-2)]^2+[8-14]^2}\implies BC=\sqrt{(3+2)^2+(8-14)^2} \\\\\\ BC=\sqrt{25+36}\implies BC=\sqrt{61}\implies \stackrel{\textit{rounded up}}{BC=7.8}$

Solve for x in the equation x squared + 2 x + 1 = 17.

lbvjy [14]

Answer:

Step-by-step explanation:

x^2 + 2x + 1 = 17

x^2 + 2x = 17 - 1

x^2 + 2x = 16

x^2 + 2x + 1 = 16 + 1

(x + 1)(x + 1) = 17

(x + 1)^2 = 17

x + 1 = sqrt 17

x = -1 (+ - ) sqrt 17

x = -1 + sqrt 17 or x = -1 - sqrt 17 <===
