The vertices of a triangle are: (-2, 4), (3, 4), and (-4,-5). Which of the following correctly classifies the triangle? OA. The triangle is a right scalene triangle.
OB.
The triangle is an acute isosceles triangle.
OC. The triangle is an acute scalene triangle.
OD.
The triangle is an obtuse scalene triangle.

probably the last option

step-by-step explanation:

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
