Question

plsss help me

Answer 1

First find the length of side AB in the given triangle by using the Pythagorean theorem.

Answer 2

The formula used for the length of a line segment is:\[\bf L=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\]

Answer 3

side be is 5 right? @genius12

Answer 4

Which is essentially the same thing as the pythagorean theorem. So take the two points A and B of the triangle, find their coordinates, and plug in the x and y values to find the length of side AB. Then multiply it by a scale factor of 2 to find the new length of triangle A'B'C'.

Answer 5

@katlynnn Nope. Look at it again.

Answer 6

but isnt 3^2+4^2=25
square root of 25 is 5 isnt it ? @genius12
