C would equal 20. because 12 times its self plus 16 times its self equals 400. then I square 400 and got 20, which equals c
2×+y=0,
×-y=6
Add the 1st to the 2nd equation==> 3x +y-y=6+0==> 3x=6 & x=2
Plug 2 into any of the equation & you will get y=-4
30 + 2 = 32
Yes I think it really is the correct answer
Answer:
A( multiply both sides by 6)
As seen , the L.C.M is 6 so to do away with the fractional form, we will multiply by 6
