Please help me please

it is A and C

Step-by-step explanation:

If you do the math and equations of all of these, you will find that:

10 is 2.5x bigger than 4 (Side lengths DE and BA)

and if we do the equation:

x · 2.5

(the x variable stands for the different side lengths of triangle ABC)

it will equal the side lengths of the bigger triangle.

and when I finished doing that, I multiplied all of the answers to find the area:

12.5 x 7.5 x 10 which altogether is 937.5

none of the other answers for the total of the triangle add up to be that, but side length EF is 7.5, which I used to get my total answer of 937.5.

So the answer is A and C

f(x) = y

f(-3) = -5

step-by-step explanation:

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
