Factor out the leading coefficient:
Now complete the square:
Now, redistributing the leading
gives
7.47/3 = 2.49. 2.49 is the base cost per yard. 2.49*2 is 4.98. The extra fabric will cost him $4.98
Also pro tip always put the unit of measurement in when describing, whether it'd be a dollar sign or other thing.
Answer:
(n-2)×180=1080
180n -360=1080
180n = 1080+360
180n =1440
dividing by 180
n=8
hence it is a regular polygon with 8 sides .I.e it is an octagon
Step-by-step explanation:
we are given the total interior angles in the polygon and we know that the formula to find the total interior angles of a polygon is (n-2) ×180
where n is the number of sides
I'm pretty sure it'd just be a parabola with is axis at 0 facing upwards and the inverse would be facing downwards
B. 2/3
bcuz there are 3 slices and 2 of them are shaded
