Answer:
nswer:
(x-1) is factor of our function.
Step-by-step explanation:
We are given a function and we are asked to find the correct factor from the given options.
Let us factor out our polynomial.
Therefore, (x-1) is correct choice for factor of our polynomial.
Step-by-step explanation:
20) 13=2f+5
2f=8
f=4
6x<=3
x<=1/2
-f-5(2f-3)=-f-10f+15=-11f+15
answer B
45+0,15*45=45+6,75=51,75$

Answer: D. regular hexagon</h3>
A hexagon is composed of 6 congruent equilateral triangles. Each equilateral triangle has interior angle of 60 degrees. Adding 6 such angles together gets you to 360 degrees. So we've done one full rotation and covered every bit of the plane surrounding a given point. Extend this out and you'll be able to cover the plane. A similar situation happens with rectangles as well (think of a grid, or think of tiles on the wall or floor)
In contrast, a regular pentagon has interior angle 108 degrees. This is not a factor of 360, so there is no way to place regular pentagons to have them line up and not be a gap or overlap. This is why regular pentagons do not tessellate the plane. The same can be aside about decagons and octagons as well.
Answer:
59.15 in^2
Step-by-step explanation:
Using Heron's formula
semiperimeter , s = 1/2 ( 28.8+18+12) = 29.4
Area = sqrt ( 29.4(29.4-28.8)(29.4-18)(29.4-12) ) = 59.15 in^2
