Answer:
-2
Step-by-step explanation:
We have to multiply 10 and 
Here we have to distribute the negative sign.
Distributive property = -(a) = -a
Using the above property, we get
= 
Now we have to multiply 10 and 
= 10 × 
= 
=

= -2
Answer:
16
Step-by-step explanation:
adding any two sides of a triangle is allways greater than the third side
Yes
remember you can do anything to an equaiton as long as you do it to boh sides
ad try to get unknown to one side
9n-10=4n+10
minus 4n both sides
9n-4n-10=4n-4n+10
5n-10=0+10
add 10
5n+10-10=0+10+10
5n+0=20
5n=20
divide both sies by 5
5n/5=20/5
5/5n=4
1n=4
n=4
