$5x^2 - 2x - 3$

$5x^2+3x-5x-3$

$x(5x+3)-(5x+3)$

$(5x+3)(x-1)$

Factoring is the only solution.

What is the span of the roof? A. 4 ft B. 12 ft C. 18 ft D. 24 ft

RoseWind [281]

Answer:

D. 24 ft

Step-by-step explanation:

The slope of 1/3 means the rise is 1/3 the run for each half of the span. The rise is shown as 4 ft, so the half-span is 3·4 ft = 12 ft.

The span of the roof is 24 ft.

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

\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 6 &,& 9~) 
% (c,d)

% distance value
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
d=\sqrt{(10-6)^2+(15-9)^2}\implies d=\sqrt{4^2+6^2}\implies d=\sqrt{52}
\\\\\\
d\approx 7.2$

what's its speed? well, it traveled √(52) in 2 seconds, so is simply √(52)/2, which is about 3.6 units per second.
