Try taking it one step at a time and multiplying each set one by one. watch the negative signs! remember: a negative times a positive is negative, and a negative times a negative is positive!
-2m(m+n-4)= -2m^2 -2mn+8m
next:
5(-2m+2n) = -10m+10n
next:
n(m+4n-5) = nm + 4n^2-5n
you're left with
-2m^2-2mn+8m-10m+10n+nm+4n^2-5n
now, add "like terms" (aka terms that have the same letters and powers, like 10n and -5n)
So,
-2m^2-nm-2m+5n+4n^2
is your answer! (answer choice C.)

Answer:
x=11 degrees
Step-by-step explanation:
First what you would do is add 6x and 5x-7 to get 11x-7 degrees. Then you double that by using opposite angles theorem to get 22x-14 as the answer of two angles. Next you double 7x-11 to get 14x-22 by using the same theorem as the last one. then you do 14x-22+22x-14=360 degrees then you get your final answer of x=11 degrees
Answer:
isn't it x=9..?
Step-by-step explanation:
3x+1=2x+10
3x-2x=10-1
x=10-1
x=9
the equation becomes:
Step-by-step explanation:
This equation shows a way to find a fraction equivalent to 16\18 enter numbers below to correctly complete the equations.
The equation is:
Both the numerator and denominator should be divided by the same term.
So, 16/2 = 8
and 18/2 = 9
So, the equation becomes:
