You still carry the decimals when subtracting fractions, if there is a decimal in the problem.
<h3>
Answer: 20 sides</h3>
Work Shown:
E = exterior angle = 18 degrees
n = number of sides of a regular polygon
n = 360/E
n = 360/18
n = 20
This is a 20 sided regular polygon. It is considered a regular icosagon.
<span>x^4+2x³-8x-16
-------------------
x + 2
</span> x^3(x+2) - 8(x+2)
= --------------------------
x + 2
(x+2) (x^3 - 8)
= -----------------------
x + 2
= x^3 - 8
= (x - 2)(x^2 + 2x + 4)
answer
(x - 2)(x^2 + 2x + 4)
Answer:
17
Step-by-step explanation:
k(x)=-2x^2+10x+5
k(3)=-2(3)^2+10(3)+5
k(3)=-2(9)+30+5
k(3)=-18+35
= 17
