A line segment has endpoints (-2,-3) and (4,4). Find the length of the segment and find the midpoint.

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}

\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ -2 &,& -3~) 
% (c,d)
&&(~ 4 &,& 4~)
\end{array}
\\\\\\
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
d=\sqrt{[4-(-2)]^2+[4-(-3)]^2}\implies d=\sqrt{(4+2)^2+(4+3)^2}
\\\\\\
d=\sqrt{36+49}\implies \boxed{d=\sqrt{85}}\\\\

Factor to find all possible values for x:2x²+7X+5=0

AlexFokin [52]

Answer:

D. x = -5/2, x = -1/2

Step-by-step explanation:

2x² + 7x + 5 = 0

(2x + 5)(x + 1) = 0

2x + 5 = 0 or x + 1 = 0

2x = -5 or x = -1

x = -5/2 or x = -1/2
