Answer:
1.6
Step-by-step explanation:
if you divide 16.8 by 4.5 you get 3.7 now 3.7 divided 2.3 = 1.6
First, find any zero of the polynomial. Since you didn't ask for work, I'll assume it's okay if I use my calculator. Your given polynomial has only one real root which is x=-4.
Now we use the rule that x-a divides the polynomial where a is a zero of said polynomial.
So x+4 divides 2x^3+2x^2-19x+20.
<span>(2x^3+2x^2-19x+20) / (x+4 equals 2x^2-6x+5).
If we factor out a two, we can use the quadratic formula.
2(x^2-3x+2.5) so we have x = (-(-3)+/-(9-4*1*2.5)^(1/2))/2*1)=(3+i)... or (3-i)/2 Where i is the square root of negative one. final answer:
2x^3+2x^2-19x+20=0
then x=-4, (3+i)/2, or (3-i)/2
</span>we have two imaginary number.
I hope it helped you
Is there something like a picture so I can understand better?
Hello from MrBillDoesMath!
Answer:
3 1/2 (i.e 3.5)
Discussion:
From the attached file, the area of the shaded triangle =
Area = <u>square</u> surrounding triangle -
area triangle 1 - area triangle 2 - area triangle 3
= 4 * 4 -
(1/2) (1 * 1) - (1/2) (3 * 4) - (1/2) (3 * 4)
= 16 - 1/2 - 1/2 (12) - 1/2(12) =
= 16 - 1/2 - 12 =
= 4 - 1/2
= 3 1/2
Where we have used that the area of a triangle =
(1/2) base * height.
Thank you,
