Question

Math need help. K12 I don’t understand. Book and lesson no help

Answer 1

Part 1

The correct answer is figure 3

Part 2

the correct answer is figure 1

Explanation:

Dilation means changing the shape of an object. In mathematics dilation is refereed to change the size of a shape. If we see figure 1 it shows 2 cm and the question says in part 1 that if figure 1 is pre image then which image is dilation by 4 so as we see that 2 x 4 gives us 8 so the answer would be figure 3 because it actually shows 8. If figure 1 was given as 1 cm then figure 2 would be the answer.

Part 2

If figure 2 is the pre image then 1/4 will be 2 x 1/4 2hich means the answer should be 2 and we see that it is figure 1.

Because 2 x 1/4 will give us 2/4 and it will be 2. Which is the size of figure 1.

Answer 2

Figure 3

Figure 1

Explanation:

Figure 1 is the pre-image

The side length is 2. We multiply the side length by the scale factor.

2 * 4 = 8

The new figure will have a side length of 8. That will be Figure 3

Figure 2 is the pre-image

The side length is 4. We multiply the side length by the scale factor.

4 * 1/2 = 2

The new figure will have a side length of 2. That will be Figure 1
