Answer:

10x^3 - 34x^2 + 33x - 7

Step-by-step explanation:

Multiply each term of the trinomial by each term of the binomial. Then combine like terms.

(2x^2 - 4x + 1)(5x - 7) =

= 10x^3 - 14x^2 - 20x^2 + 28x + 5x - 7

= 10x^3 - 34x^2 + 33x - 7

Answer:  10x³ -34x² +33x - 7

<u>Step-by-step explanation:</u>

 (2x² - 4x + 1)(5x - 7)

= (5x - 7)(2x² - 4x + 1)

= 5x(2x² - 4x + 1)   -7(2x² - 4x + 1)

= 10x³ - 20x² + 5x    

<u>  +         -14x² + 28x - 7</u>

= 10x³ - 34x² + 33x - 7

If K is the midpoint of JL , JK = 6x + 11 and KL = 16x +1, find JL.<br> Pls I need help
Korvikt [17]

Since K is the midpoint of JL and we know that JK and KL are separate segments of JL, JK and KL are equal to each other.

6x + 11 = 16x + 1

Subtract 6x and 1 from both sides

10 = 10x

Divide both sides by 10

1 = x

We also know that:

JL = JK + KL = 6(1) + 11 + 16(1) + 1 = 6 + 11 + 16 + 1 = 34

Answer:

question no:3

Step-by-step explanation:

here

= x^2 + 5x - 300

= x^2 +(20-15)x -300

= x^2 + 20x - 15x - 300

= x(x+20) -15(x+20)

= (x+20) (x - 15)

Write equation of a line perpendicular to the y-axis that passes through the point (-4,-8)
babymother [125]

Answer:

y = -8

Step-by-step explanation:

Since the line is perpendicular to the y-axis, it will be a horizontal line that runs through (-4,-8).

When a line is perpendicular to the y-axis, the x-coordinate doesn't matter because the line will be horizontal, meaning it will be the same y value regardless of the x value. In this case, the y value is −8 throughout the line.
