Triangle CDE with vertices C(-1,3), D(4,2), and E(3, 1): a) translated along the vector ( 3, -7)
b) 270° counterclockwise rotation about (2, -3)
What are the coordinates of C’, D’, E’, and C’’, D’’, E’’ ?

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

i need points

step-by-step explanation:

sorry bubs

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
