x3 × x3 × x3 (I'm assuming you mean 3x for that) is equal to 9x^3. x3 × 3 × 3 is equal to 9x. They are not equivalent because one expression has 3x, 3 times, because you are multiplying the 3's together, and adding the x's three times, you get 9x^3. The x's are important since it differentiates between both expressions. 3x × 3 × 3, there is only one x in it, so it is just 9x. Does 9x=9x^3? No.
Answer:
<h2>The third option is correct.</h2>
Step-by-step explanation:
The line D'E' is parallel to the y-axis.
Hence, it is clear that the image is reflected across the y-axis.
If you see closely the given image, you can see that the y ordinates of each point of the Pentagon has shifted 8 points towards the positive direction of y-axis.
Hence, the transformation for the y-coordinates will be Y = y + 8.
Now if you check the transformation for the x-coordinates, you will observe that the coordinates of D and E will be lie on x = -1. After reflection, they will lie on x = 1.
x^2-9x+18=0
So I'm gonna solve it as if you need to find the x values
So 18 is positive and 9 is negative, so we have to find 2 values that multiply to +18 but add to a -9
Which is negative 3 and negative 6. double - = +
(x-3) (x-6)
x intercepts ---> x= 3 x= 6
