Answer:
8x²+6x+12xy+9y
Step-by-step explanation:
⇒(-2x - 3y)(-4x - 3)
⇒(-2x × -4x)+(-2x × -3)+(-3y × -4x)+(-3y × -3)
⇒8x²+6x+12xy+9y
Since it’s a trapezoid, 111 + b will equal 180, as will 41 + a.
111 + b = 180 means b = 69.
41 + a = 180 means a = 139.
This happens simply because two angles that are positioned that way between parallel lines will always be supplementary. It’s also worth noting that all angles in any quadrilateral will add up to be 360 degrees.
Well, he reads 48 pages in those 12 days, that is 12*4 pages.
He has already read 48 pages and he still has 82, so he has a 130=48+82 page book.
