serg [7]

Answer:

3x(3x³ + 8x² – 9x + 4)

Step-by-step explanation:

9x4 + 24x3 - 27x2 + 12x =

9x⁴ + 24x³ – 27x² + 12x =

3(3x⁴ + 24x³ – 27x² + 12x) =

3x(3x³ + 24x² – 27x + 12).

3x³ + 24x² – 27x + 12 cannot be factored

Inessa05 [86]

9514 1404 393

Answer:

  6x -7 units

Step-by-step explanation:

Let c represent the length of the third side. The perimeter is the sum of the three side lengths.

  P = a + b + c

  (17x -5) = (3x +5) +(8x -3) +c

 17x -5 = 11x +2 + c . . . . . . . . . . . . collect terms

  6x -7 = c . . . . . . . . . . . . . . subtract 11x+2

The third side is 6x -7 units.

What is the equation of the line that passes through the point (-6, -6) and has a<br> slope of - 1/3
pickupchik [31]

Answer:

The equation of the line is y = -\frac{1}{3}x - 8

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

y = mx + b

In which m is the slope and b is the y-intercept.

Slope of - 1/3

This means that m = -\frac{1}{3}

So

y = -\frac{1}{3}x + b

Through the point (-6, -6)

This means that when x = -6, y = -6. So

y = -\frac{1}{3}x + b

-6 = -\frac{1}{3}(-6) + b

b + 2 = -6

b = -8

The equation of the line is y = -\frac{1}{3}x - 8
