What must the measure of angle LMN be? m∠LMN = °

luda_lava [24]

Both 25x and 22x + 9 have the same answers. So you set those two equal to each other.
$25x = 22x + 9$
Subtract 22x from both sides.
$3x = 9$
and you're left with this.
Next, divide 3 from both sides.
$x = 3$
re-insert 3 into one of the equations.
$25(3) = 75$
add up both angles
$75 + 75 = 150$
all angles (for quadrilaterals)added up equals 360.
$150 + 2x = 360$
solve for x. Subtract 150 from both sides.
$2x = 210$
and divide 2 from both sides
$x = 105$
AngleLMN= 105

(2a^x +1/2 b^x)^2 thank you!!!!!!!!!!!!!!!!!!!1

kogti [31]

Note that (a+b)^2 = a^2 + 2ab + b^2.

Therefore,
b^x (b^x )^2
(2a^x +1/2 b^x)^2 becomes (2a^x)^2 + 2(2a^x)(-------- ) + ------------
2 4

LCD is 4. Thus, we have

4 [ (2a^(2x) ] + 8a^x*b^x + b^(2x)

PLEASE HELP ASAP! Several books are placed on the bottom three shelves of a bookcase. When 1 book was taken from the first shelf

sergeinik [125]

Answer:

24 books

Step-by-step explanation:

Initially the top shelf has no books placed on

Then books added to this:

1+2+3= 6

And now all 4 shelves have same amount of books. So total number is:

4*6= 24 books

There are 24 books in the bookcase
