Answer:
- octagon
- irregular polygon
- concave
Step-by-step explanation:
The figure has 8 sides that are each line segments joined at the ends. An 8-sided polygon is called an <em>octagon</em>. Though the sides are the same length, not all angles are congruent, so the polygon is <em>not a regular polygon</em>. Some of the angles are reflex angles, so the polygon is <em>concave</em>, not convex.
Y = 3x² - 9x + 12
y' = 6x - 9 = 0
6x = 9
x = 9/6 = 3/2

Answer:
-1.9
Step-by-step explanation:
He has $1.10 in his printing account. 0.25 each sheet of paper.
47 pages.
He printed both sides so 47:2= 23.5.
Because he printed 2 pages then we divide by 2.
23.5:2=11.75
We cannot print a half of page, so we print 12 pages.
12*0.25=3
1.10-3=-1,9
His printing account will be in minus.
