Answer:

B. 6 is also a factor of this trinomial.

Step-by-step explanation:

We have been given a trinomial 6x^2-18x+12. A student gives the answer (x-2)(x-1).

To figure out student's mistake, let us factor our given trinomial by splitting the middle term.  

6x^2-18x+12    

6x^2-12x-6x+12    

6x(x-2)-6(x-2)    

(6x-6)(x-2)    

6(x-1)(x-2)  

Therefore, 6 is also a factor of our given trinomial and option B is the correct choice.

Answer:

7.1 units is the answer

Step-by-step explanation:

d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{(6-1)^2 + (2-7)^2}\\\\d=\sqrt{(5\\)^2+(-5)^2} \\\\d=\sqrt{25+25} \\\\d=\sqrt{50} \\\\d=7.071..

Rounding off,

d = 7.1 units

Please help me with this problem <br> Evaluate (-½·3)³
-Dominant- [34]

Answer: -27/8

Step-by-step explanation:

\left(-\frac{1}{2}\cdot \:3\right)^3

\mathrm{Apply\:exponent\:rule}:\quad \left(-a\right)^n=-a^n,\:\quad \mathrm{if\:}n\mathrm{\:is\:odd}

\left(-\frac{1}{2}\cdot \:3\right)^3=-\left(\frac{1}{2}\cdot \:3\right)^3

=-\left(\frac{1}{2}\cdot \:3\right)^3

\mathrm{Apply\:exponent\:rule}:\quad \left(a\cdot \:b\right)^n=a^nb^n

\left(\frac{1}{2}\cdot \:3\right)^3=\left(\frac{1}{2}\right)^3\cdot \:3^3

=-\left(\frac{1}{2}\right)^3\cdot \:3^3

=-\frac{1}{8}\cdot \:3^3

=-\frac{1}{8}\cdot \:27

=-\frac{27}{8}

Graph the image of this figure after a dilation with a scale factor of 2 centered at (2, 2).
Maru [420]

Answer:

(-6,6), (0,12), (4,8)

Step-by-step explanation:

To dilate an object, we need to multiply the x and y values by the given scale factor.

In this case the scale factor is 2 --> 2(x, y)

Before-> After dilation

2(-3,3) = (-6,6)

2(0,6) = (0,12)

2(2,4) = (4,8)

Please leave a 'thanks' if this helps!
