Answer:

The remainder after dividing  x4 + 3x3 − 8x2 + 5x − 9 by x + 5 is 16

Step-by-step explanation:

We have to divide x4 + 3x3 − 8x2 + 5x − 9 by x+5

First of all we solve the first term of the dividend.

We have the divisor x+5

If we multiply it by x^3 than we get the first term of our dividend.

x^3(x+5) = x^4+5x^3

x4 + 3x3 − 8x2 + 5x − 9

x^4+5x^3

-      -

___________________

     -2x^3-8x^2+5x-9

Now we have the first term of dividend as -2x^3

Now we will multiply x+5 by -2x^2 to get the first term

-2x^2(x+5) =  -2x^3-10x^2

-2x^3-8x^2+5x-9

-2x^3-10x^2

+       +

______________

        2x^2+5x-9

Now the first term of the dividend is 2x^2

So we will multiply x+5 by 2x

2x(x+5)= 2x^2+10x

 

2x^2+5x-9

2x^2+10x

-       -

_________

       -5x -9

Now the dividend we have is -5x-9

We will multiply x+5 by -5

-5(x+5) = -5x-25

-5x -9

-5x-25

+    +

______

      16

Thus the remainder after dividing  x4 + 3x3 − 8x2 + 5x − 9 by x + 5 is 16....

Factor x^2 - 7x + 12 please explain how you got your answer
Gekata [30.6K]
(x - 4)(x - 3), First find the factors of x^2 which is x and x so write that down of the left sides of both brackets. Next, find the factors of 12 that when added gives you the middle number which is -7 and i got 3 and 4 so write that down in the right sides in the brackets. Lastly you need to know the signs so now since its + 12 you need the signs that give you a positive number which is - and - but its also + and +, so look at the middle number its -7x so +3 +4 wont give you -7x but -3 - 4 will so that your answer, 
Hope this helped!

Jaime has 5 over 11 spaceof a project completed while Tim has finished 7 over 13 spaceof the same project.
lina2011 [118]

Tim has completed greater amount of work and overall they have completed 142/143 of the project work

Step-by-step explanation:

Given

Work completed by Jaime = j = 5/11

Work completed by Tim = t = 7/13

<u>a. Who has completed the greater amount of work?</u>

In order to see that we have to convert the fractions in decimal

So,

j = 5/11 = 0.45

t = 7/13 = 0.53

As we can see that the decimal for Tim's work space is large, Tim has completed greater amount of work

b. How much of the project have they completed together? Show your work.

We have to find the total work done by them

Total\ work = j + t\\= \frac{5}{11} + \frac{7}{13}\\=\frac{65+77}{143}\\=\frac{142}{143}

Hence,

Tim has completed greater amount of work and overall they have completed 142/143 of the project work

Please solve question in picture branoist to first and correct​
Oliga [24]

Answer:

The correct answer is Option 3: 12y

Step-by-step explanation:

A polynomial term is usually made of a variable and a co-efficient.

Like terms are those terms that have the same variables i.e. x and 44x are like terms.

Given expression is:

6y-2y+8y

All the terms have only y which means that all three terms are alike.

The coefficients of like terms are added or subtracted according to their sign.

6y-2y+8y = 12y

Hence,

The correct answer is Option 3: 12y
