-3x(x+8)+x+2(9-x-x^2) please show solving steps
Flauer [41]

Answer:

-5x^2 - 25x + 18

Step-by-step explanation:

-3x ( x + 8 ) + x + 2 ( 9 - x - x^2 )  ( original equation )

-3x^2 - 24x + x + 18 - 2x - 2x^2   ( distribute )

-3x^2 - 2x^2 - 24x + x - 2x + 18   ( order them based on the variables . )

( -3x^2 - 2x^2 ) (- 24x + x - 2x ) ( + 18 )    ( just separated them not a part of solving !! )

-5x^2 - 25x + 18    ( solved , and the answer :) )

Hope its helps !!!

a class has 60 students.Given that 85% passed a science test. Find the number of students who failed and then convert o %
Vanyuwa [196]

Given:

Total students = 60

Student passed = 85%

To find:

The number of students who failed and  then convert it in %.

Solution:

We have,

Number of passed student = 85% of Total students

                                            = \dfrac{85}{100}\times 60

                                            = 51

So, number of passes students is 51.

Number of students who failed = Total students - Passes students

                                                    = 60-51

                                                    = 9

So, number of students who failed is 9.

\text{Fail}\%=\dfrac{\text{Failed students}}{\text{Total students}}\times 100

\text{Fail}\%=\dfrac{9}{60}\times 100

\text{Fail}\%=15

Therefore, 15% students fail in the test.
