i need to write an expression for the shaded region in its simplest form, showing all of my steps!

but it's late at night and i'm not entirely sure how to do this, so you so much in !

x² + 23x + 49

Step-by-step explanation:

Area of the big rectangle

= (x + 10)(2x + 5)

= 2x² + 5x + 20x + 50

= 2x² + 25x + 50

Area of the small white rectangle

= (x + 1)(x + 1)

= x² + x + x + 1

= x² + 2x + 1

Area of the shaded area

= (2x² + 25x + 50) - (x² + 2x + 1)

= 2x² + 25x + 50 - x² - 2x - 1

= x² + 23x + 49

anser is a

step-by-step explanation:

negitive slope

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
