Answer:

Step-by-step explanation:

To calculate the scale factor k, find the ratio of corresponding sides

$\frac{XZ}{AC}$ = $\frac{18}{3}$ = 6

$\frac{YZ}{BC}$ = $\frac{24}{4}$ = 6

Hence the scale factor k = 6 → A

tensa zangetsu [6.8K]

Answer:

There are four possible rectangles with 10 tiles.

Step-by-step explanation:
The question for this problem is: How many different rectangles could she make with the 10 tiles?

All the dimensions possible are all products that give 10 as a result. So, all possible rectangles would be:
2 width x 5 length = 10
5 width x 2 length = 10
1 width x 10 length = 10
10 width x 1 length = 10

kow [346]

Answer:

The correct option is B.

Step-by-step explanation:

The given vertices are (-4,2),(1,2),(1,-3) and (-4,-3).

Plot these point on a coordinate plate. From the graph it is noticed that the given quadrilateral is a square.

Distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
