slope intercept form equation, y = mx + b
answer, y = -2x + 4
3^2 = 9
9/9 = 1
1 + 12 = 13
This is based on the Order of Operations.
Hope it helps! :D
The answer would be twenty: 20
156÷13
13 goes into 15 once
so under the 156 put 13 under 15 left with 2 bring down the 6 to make it 26
13 goes into 26 2 times
so under where you wrote 26 put 26 then 26-26=0
so your answer is 12
