The scale factor is (x2)!

9×2 = 18
4 1/2 × 2 = 9

Answer:   0.5

Step-by-step explanation:

We know that the scale factor for dilation is the ratio of the side-length of the image to the side-length of the pre-image.

From the given figure, In Pre-image ΔABC , we have  AC=18              

In Pre-image ΔA'B'C', we have A'C'=9          

Now, the scale factor will be :_

k=\dfrac{A'C'}{AC}=\dfrac{9}{18}=\dfrac{1}{2}=0.5

Now, the scale factor for this dilation = 0.5

Factor by Grouping 8x+8y+rx+ry<br> I do not understand this.
nadezda [96]
FACTORISATION IS BASICALLY FINDING LIKE-TERMS.
1. FIND THE HCF OF 8. HERE, THE HCF IS 8. ALSO, CHECK ALL THE LIKE-TERMS. LIKE-TERMS ARE OUTSIDE THE BRACKET AND UNLIKE TERMS ARE INSIDE.
2. ADD THE TERMS IN THE BRACKET AND THE TERMS OUTSIDE THE BRACKET FROM STEP 1.

8x + 8y + rx + ry
1. 8 (x + y) + r (x + y)
2. (x +y) (8+r)

The length of a rectangle is 2 meters less than 2 times the width. The perimeter is 20 meters. Find the width.
kakasveta [241]
The equation you'd make would be (2x-2)+(2x-2)+x+x=20 because the length is 2 m less than the width (x). To simplify, it'd be 6x-4=20 because you combine like terms. You then move the -4 over to the 20 to make it 6x=24. The final answer is 4 meters.
