"D" Is Your Answer .
0.4 Times 0.3 = 0.12
If they all have the same variable it will be much easier to solve cause they’re all like terms. so you just take 10-5 which is 5 plus 3 which is 8 and 8 minus 8 is 0.
To check it we can use Pythagorean theorem.
, where c is the longest side.
Lets check it
Assume that a=10 and b= 24
Now lets compare with c^2=676
Its equal, so its right triangle.
