A triangle has vertices A(0, 0), B (9,4), and C(-2, 10). What are the coordinates of the triangle after a dilation with a scale factor of 1?

OA' (0,0), B'(18,8), and C'(-4, 20)

O A' (0,0), B'(-4.5,-2), and C (1,5)

O A'(0,0), B'(3, 2), and C’ (0, 5)

O A' (0,0 ), B'(4.5, 2), and C'(-1,5)

a

step-by-step explanation:

the answer is a

my best guesses would have to be either 4.5 or 2. p.s. if they're wrong, i'm so sorry for giving you the wrong answer.

step-by-step explanation:

1 simplify brackets

-\frac{8}{9}\times \frac{5}{6}−
