[5(14-2)^2]/2=
(5•12^2)/2=
5•144/2=
5•72=
720/2= 360
It would actually be -14 because 5+4-2=7 and if you multiply 7 by -2 you get -14
Answer:
x=12.5
Step-by-step explanation:
0.7x times (-1.4)=-3.5
-0.28x=-3.5 (divide both sides)
Ans:12.5
So 12/15 simplifies to 4/5, and if you multiply both sides by two you have 8/10 so i guess 2 ( and some extra )
You know that you need two already to make one hexagon. So, if you multiply, or add two four times, 2+2+2+2, you would get eight.
