To find out if the triangle is a right triangle, we must check if the following equation is true:

$(15)^2+(20)^2=(25)^2^{}^{}^{}$

on the left side, we have:

$(15)^2+(20)^2=225+400=625^{}$

and on the right side, we have:

$(25)^2=625$

since on both sides we get 625, we have that the brace forms a right triangle.

Perimeter of a triangle = all 3 sides added together

x + (x - 4) + (x - 4) = 19
3x - 8 = 19
3x = 19 + 8
3x = 27
x = 27/3
x = 9 <==

I would multiply 46x1x1,000 to get 46,000. the. i would multiply 1x2.2x1 to get 2.2. i would then divide 46,000/2.2 to get 20,909.0909
