Answer:

I'm pretty sure it's 24.05

Step-by-step explanation:

6.5 x 7.4 = 48.10

48.10 ÷ 2 = 24.05

13.8 if you multiply 6.5 then 7.4 then 1/3 you get 13.8

Answer:

$\{(0,0) (0,9) (9,0)\}$

Step-by-step explanation:

Given

See attachment for matrix

From the attachment, we have the following vertices

$(x_1,y_1) = (0,0)$

$(x_2,y_2) = (0,3)$

$(x_3,y_3) = (3,0)$

When scaled by 3T, we have the following:

$(x_1,y_1) =3 * (0,0)$

$(x_1,y_1) =(0,0)$

$(x_2,y_2) = 3 * (0,3)$

$(x_2,y_2) = (0,9)$

$(x_3,y_3) = 3 *(3,0)$

$(x_3,y_3) = (9,0)$

Hence, the vertices are:

$\{(0,0) (0,9) (9,0)\}$
