Factor completely and then place the factor. in the proper location on the grid (4x-+3)(-2x-5)
Ivahew [28]
Yay, love these ones.

First of all, (4x-+3)(-2x-5) is the same as (4x-3)(-2x-5)
So the method for solving these can be remembered by FOIL.
F= Firsts   O= Outsides   I= Insides   L= Lasts

In other words everything is multiplied by everything, for example:
4x * -2x and -3 * -5 <span>is the firsts of the brackets multiplied and last of the brackets mulitplied
</span>
4x * -5 and 3 * -2x is the outsides of the brackets multiplied and the insides of the brackets multiplied
<span>
The SUM of FOIL is then added:</span><span>
</span><em>4x*-2x = -8x^2</em>
<em>-3*-5= 15</em>
<em>4x*-5=-20x</em>
<span><em>3*-2x=-6x</em>
</span><span>-8x^2 -20x -6x + 15 = 0
-8x^2 -26x + 15 = 0

So the factored of (4x-3)(-2x-5) <u /><em>=</em> -8x^2 -26x + 15 = 0

So then you graph that equation on your given grid

Pleaseeee help me!!! DUE IN 15 MIN​
MA_775_DIABLO [31]

Answer:

∠Y = 55°

Step-by-step explanation:

Since triangle ABC and XYZ are congruent, that means that...

∠A = ∠X

∠B = ∠Y

∠C = ∠Z

Since ∠Y = ∠B and ∠B = 55°, that means ∠Y = 55°.
