What is the product? (4y - 3) (2y^2 +3y - 5)
igomit [66]

(4y-3)(2y²+3y-5)

First , let's start with "4y"

4y*2y² = 8y³

4y*3y =  12y²

4y*-5 = -20y

Next, let's multiply by "-3"

-3*2y² = -6y²

-3*3y = -9y

-3*-5 = 15

Now, let's combine all of our values.

8y³+12y²-6y²-20y-9y+15 = 8y³+6y²-29y+15

Prove that in each triangle the total angles are 180 degrees
dmitriy555 [2]

This is a proof that the angles in a triangle equal 180°:

The top line (that touches the top of the triangle) is
running parallel to the base of the triangle.

So:

<span> <span>angles A are the same </span> <span>angles B are the same </span> </span>

And you can easily see that A + C + B does a complete rotation from one side of the straight line to the other, or <span>180°</span>
