10,3,5

Obtuse triangle

Step-by-step explanation:

right triangle:

c² = a² + b²

10² = 3² + 5²

100 = 34 NO!

acute triangle:

c² <  a² + b²

10² < 3² + 5²

100 < 34 NO!

Obtuse triangle:

c² > a² + b²

100 > 34 YES

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
