lianna [129]

Answer:

444,444

Step-by-step explanation:

total amount=737373

jerry=292929

Brandon=unknown

To figure the amount of video games Brandon has, we have to subtract the amount of both he and his friend altogether amount with Jerry's current amount of video games.

737,373-292,929=444,444

So, by subtracting the two, the answer would be 444,444.

Brandons total amount of video games:444,444

Find the roots of the polynomial equation.<br><br> 2x3 + 2x2 – 19x + 20 = 0
d1i1m1o1n [39]
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

Jake has 1 yard of cloth. He makes bookmarks that are each 1 1/8 inches long. How many bookmarks can he make?
PolarNik [594]
<span>Jake has 1 yard of cloth. He makes bookmarks that are each 1 1/8 inches long.
Let’s find out how many bookmarks can he make.
Unit of conversion:
=> 1 yard = 36 inches.
Now, he divided it to 1 and 1/8 inches
=> 1 and 1/8 = 1.125 inches
So let’s divide this with 36 inches
=> 36 / 1.125 = 32
Thus jake can make a total of 32 bookmarks out of 1 yard of cloth with a measurement of 1 and 1/8 inches.
