Answer:
That is an obtuse scalene triangle
Step-by-step explanation:
Scalene- has no congruent sides
Obtuse - has an angle that is greater than 90
we can use Pythagorean theorem to confirm this
The Pythagorean theorem states that in an obtuse triangle the hypotenuse squared is greater than the two legs squared added together
so basically 
therefore it is an obtuse scalene

Answer:
12 inches
Step-by-step explanation:
So you know that the perimeter of a picture frame (a rectangle) is 2 widths plus 2 lengths.
Let x= lengths and w= widths
From the question we already know that w=7, so we can set up an equation that says:
2x + 2w = 38
2x + 2(7) = 38
2x+14 = 38
2x +14 -14 = 38-14
2x = 24
2x/2 = 24/2
x= 12
Since x= lengths =12
the length of the frame is 12 inches.
The slope of 2x - y = 9 is 2x
