Oh these are easy, I’ll explain.
To start off, the answer is 11.
I got this by subtracting DE (57) and BC (35). You get 22. Then, you divide the result of the subtraction by 2, which is 11.
Let me know if you need me to explain in more depth, and give brainliest if I’m correct tysm.

Answer:
−10x4+17x2y−6y2-10x4+17x2y-6y2
or the second option




= Let Martina's cousin's age be = n
= Let her age be = n+12
After four years,
Cousin's age = n+4
Her age = n+12+4=n+16
But according to the question her age = 3(n+4) = 3n+12
Thus,
3n+12=n+16
3n-n=16-12
2n=4
n=4/2

Thus ,
Her cousin's present age = n = 2
Her cousin's present age = n = 2Her present age = n+12 = 2+12=14
