Answer:

=x^3-x^2-30x+72

Step-by-step explanation:

Distribute parentheses:

=xx^2+x\left(-7x\right)+x\cdot \:12+6x^2+6\left(-7x\right)+6\cdot \:12

Apply minus - plus rule:

=x^2x-7xx+12x+6x^2-6\cdot \:7x+6\cdot \:12

Simplified:

=x^3-x^2-30x+72

Its complicated but..

Step-by-step explanation:

( x + 6 ) ( x^2 - 7x + 12 )

x ( x^2 - 7x + 12) + 6 ( x^2 - 7x + 12 )

x^3 - 7x^2 + 12x + 6x^2 - 42x + 72

x^3 + 6x^2 + 12x - 42x - 7x^2 + 72

19x - 49x + 72

30x + 72

x = 72/30

x = 2.4

Write an equation in standard form for a line that passes through (2,2) and (0,-3).
asambeis [7]
So,

The standard form is:
y = mx + b

First, we find "m," the slope.  Subtract the y-coordinates from each other.  Do likewise with the x-coordinates.

2 - -3 = 5
2 - 0 = 2

Slope = 5/2

y= \frac{5}{2} x+b

Now, we can substitute the second solution into this equation for x and y and solve for "b."

-3= \frac{5}{2} *0+b

-3= b

Now we have our complete equation.

y= \frac{5}{2} x-3

Use absolute value notation to represent the distance between x and 8 is no more than 4
ivanzaharov [21]
The distance: use absolute value
Between x and 8: x-8

The distance between x and 8: | x-8 |

“is no more than” means it can be that or be less than that, so use ≤

The distance between x and 8 is no more than 4

| x-8 | ≤ 4
