Answer:

The answer to your question is the letter B. 5y³ - 18y² + 29y - 12  

Step-by-step explanation:

Data

           (y² - 3y + 4)(5y - 3)

Process

1.- Multiply the first terms by 5y

           (y² - 3y + 4)(5y) = 5y³ - 15y² + 20y

2.- Multiply the first terms by -3

            (y² - 3y + 4)(- 3) = -3y² + 9y - 12

3.- Simplify like terms

            5y³ - 15y² + 20y  -3y² + 9y - 12 = 5y³ + (-15y² - 3y²) + (20y + 9y) -12

4.- Result

                                                                = 5y³ - 18y² + 29y - 12

1/2 (x−8)+1=2( 1 8 x−1)
nalin [4]

Answer:

The solution for the given algebraic equation is \frac{ - 2}{71}

Step-by-step explanation:

Given algebraic equation as :

\frac{1}{2} ( x - 8 ) + 1 = 2 ( 18 x - 1 )

Now solving the equation while opening the brackets

So, \frac{1}{2} × x - \frac{1}{2} × 8  + 1 = 2 × 18 x - 2

Or, \frac{x}{2}  - \frac{8}{2}  + 1  = 36 x - 2

or,  \frac{x}{2}  - 4 + 1 = 36 x - 2

or,  \frac{x}{2}  - 3 = 36 x - 2

or,  \frac{x}{2} - 36 x = - 2 + 3

Or,  \frac{x}{2} - 36 x = 1

or, \frac{x - 72 x}{2} = 1

or, \frac{- 71 x}{2} = 1

∴ 71 x = - 2

I.e x = \frac{ - 2}{71}

Hence The solution for the given algebraic equation is \frac{ - 2}{71}    Answer
