If W(-10, 4), X(-3, -1), and Y(-5, 11) classify triangle WXY by its sides

As the lengths of the two sides is equal. i.e. WY =  WX . Therefore, the  triangle WXY is an isosceles triangle.

Step-by-step explanation:

Considering the triangle with the vertices

The distance between the W(-10, 4) and Y(-5, 11) is the length of the side WY.

So,

So, the length of the side WY .

Similarly,

The distance between the W(-10, 4) and X(-3, -1) is the length of the side WX.

So, the length of the side WX .

As the lengths of the two sides is equal. i.e. WY =  WX . Therefore, the  triangle WXY is an isosceles triangle.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
