Subtract 5 5⁄21 from 131⁄7 (reducing to lowest terms if necessary). A. 1019⁄7 B. 719⁄7 C. 1019⁄21 D. 719⁄21

Answers

Answer 1

Answer:

$13(1)/(7)-5(5)/(21)=13(3)/(21)-5(5)/(21)=(13-5)+\left((3)/(21)-(5)/(21)\right)\n\n=8-(2)/(21)=\left(7+(21)/(21)\right)-(2)/(21)\n\n=7+(21-2)/(21)=7(19)/(21)$

The appropriate choice is ...

... D. 7 19/21

S = 2lw + 3lh + 2wh
94 = 2(3)(4) + 2(3)(h) + 2(4)(h)
94 = 2(12) + 2(3h) + 2(4h)
94 = 24 + 16h + 8h
94 = 24 + 14h
- 24 - 24

Conjecture: How many solutions do x3 - 5x2 + 28 = 0 have? Find the real solution(s) of the equation. Then use polynomial long division to find the other solution(s).

Answers

Answer:

x = - 2 is confirmed to be the real solution of the equation.

Step-by-step explanation:

We are tasked with the following activities

Conjecture: How many solutions do $x^3 - 5x^2 + 28 = 0$ have?

Find the real solution(s) of the equation.

Then use polynomial long division to find the other solution(s).

To start with the how many solutions that $x^3 - 5x^2 + 28 = 0$ have

suppose that -2 happens to be a root of the equation, we can easily replace x = - 2 in the given equation. Then , we will have :

$(-2)^3 - 5(-2)^2 + 28 = 0$

$-8 - 5* 4 + 28 = 0$

-8 - 20 + 28 = 0

-28 - 28 = 0

0 = 0

The equation resulted to 0 = 0 when x = -2 , as such -2 happens to be one root of the equation

So , as x = - 2

x + 2 = 0

x = - 2 is confirmed to be the real solution of the equation.

A picture showing the polynomial long division method used for solving the polynomial equation and other solution(s) can be found in the attached file below.

tonight's attendance was 100 more than double the attendance last night. If 500 attended tonight, how many attended last night?

Answers

Answer: 200

Step-by-step explanation: 200 doubled would be 400 and it says that tonights attendence was 100 more than the doubled which would add up and equal 500 (400+100=500) so 200 is your answer.
