I have geometry to but i didn’t get to that yet sorry
Answer:
The answer is m = 3, -3
Step-by-step explanation:
N+(n+2)+(n+4)=51
Which isn't possible because an even plus an even equal even!
remember, you can do anything to an equation as long as you do it to both sides
try and isolate the variable you are solving for and divide it by its constant
p=2l+2w
minus 2l from both sides
p-2l=2w
divide both sides by 2


which can also be simplified to

Three plus twelve multiplied by four
