Answer:
9
Step-by-step explanation:
so any values inside the absolute value brackets | | will become positive even if they are negative, this is because absolute value represents distance from a number to 0 on a number line and you can't have a negative distance.
so
|-9|=9
and
|9|=9
hope this helps!

Let
x--------------> the complete figure
we know that
the figure is divided into 6 equal parts
x= (x/6)+(x/6)+(x/6)+(x/6)+(x/6)+(x/6)
red=(x/6)+(x/6)--------> red=(2x/6)=x/3
blue=(x/6)+(x/6)+(x/6)+(x/6)=(4x/6)=2x/3
Rashad say that 2/4 of the figure is red-------> Rashad is wrong
because (2/4) <span>It is half of the figure
</span>the correct thing is to say (1/3) o the figure is red and (2/3) of the figure is blue
w = 37.846 mph (wind rate)
plane speed in still air: 492 mph
Combine like terms:
n^3 + 20n^ + 10n^2
= n^3 + 30n^
Divide:
=n^3 + 30n^2/10n^2
Factor:
=n^2n + 30n^2
=n^(n + 30)
= 2^2(n + 30)/10n^2
Cancel the common factor n^2:
=n + 10/10
