<span>0 = x² + 10x + 16
Subtract </span><span>x^2+10x+16 from each side
</span><span>0−<span>(<span><span>x^2+10x</span>+16</span>) </span></span>= x^2+10x+16−(<span>x^2+10x+16</span>)
<span><span>−x^2−10x</span>−16</span>=<span>0
</span>
Factor left side
<span><span>(<span>−x−2</span>)</span><span>(x+8)</span></span>=<span>0
</span>
Set all factors to equal 0
<span><span><span>−x</span>−2</span>=<span><span><span>0<span> or </span></span>x</span>+8</span></span>=<span>0
</span>
The solutions are x = -2 and x = -8

The average per page will be given by:
(number of pages)/(time)
number of pages=6 pages
time=2.5 hours
thus
average=(6/2.5)=2.4 pages per hour
The answer is: 2.4 pages per hour
Answer:
as a semicircle, a hexagon, and a rectangle
Step-by-step explanation:
The first attachment shows the decomposition according to the answer choice above. It would make area computation about as simple as it could be.
__
The second attachment shows a decomposition with a circle. It leaves a very odd shape in the middle that is not easily divided into triangles, rectangles, or trapezoids.
The third attachment shows a semicircle, a pentagon, and two triangles. The pentagon is <em>not a regular pentagon</em>, so might require further decomposition in order to determine its area.
