Triangle a'b'c' is a dilation of triangle abc. which is the correct description of the dilation?

A

Step-by-step explanation:

has a length of 6

has a length of 6 + 12 = 18, which is 3 times the length of

B = B' so this will be the center point

⇒ center B and a scale factor of 3

Option A is the answer.

Step-by-step explanation:

Triangle A'B'C' is a dilation of triangle ABC.

We can apply the formula to get the scale factor as

Scale factor =

=

=

=

=

= 3

Therefore, ΔABC has been dilated with a scale factor of 3 about the point B as the center.

Option A is the answer.

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
