2.6>2.5
Answer:
X will equal 10 x=10
Step-by-step explanation:
First subtract 100 from both sides to get x^2-20x=-100 then find c. (-b/2)^2 is the formula. then c=100 so add 100 to both sides. x^2-20x+100=200. Then Factor. (x-10)^2=0 is what you should get. then do square root. x-10=0. So now add 10 to both sides and you get x=10. Tada!
Answer:
18x
Step-by-step explanation:
get the x by itself then it is 2+4=6 so that is 6x and then do 3+x=3x and 6x×3x= 18x
In brackets everything has to multiplied by 3. It there is no sign between its always multiply!!!
this means that it has to be
3 x X + 3 x 11
this means that we can also multyplay 3 by 11 now.
and that equals to 33. There fore the expansion will be:
3 x X + 33
we can also simplify 3 x X which would be 3x (as I mentioned before, It there is no sign between its always multiply!!!)
so the expansion for 3(x+11) is 3x + 33
