Answer:
Step-by-step explanation:
So the thing about adding of integers is that is both nos. are positive then you can simply add it and same with negative too.But with negative and positive we should subtract but that is for later.Luckily we have 2 positive integers so we do it like this:
+6 is the same as 6 and +2 is the same as 2 so we...
rule:add the numbers and add the sign.
Answer:
= 5x -10
Step-by-step explanation:
=(3)(3x)+(3)(−4)+(−2)(2x)+(−2)(−1)
=9x+−12+−4x+2
Combine Like Terms:
=9x+−12+−4x+2
=(9x+−4x)+(−12+2)
=5x+−10
Answer:
x = 11
Step-by-step explanation:
The angles in a square are right , that is 90°
The diagonals bisect the angles , then
6x - 21 = 45 ( add 21 to both sides )
6x = 66 ( divide both sides by 6 )
x = 11
change into improper fraction then do the problem then turn back into mixed number
