Step-by-step explanation:
since perimeter is adding all around she took the all the values and added them as above. as you can see 3√2 and 4√2 has the same square root so she added 3+4 which gave us 7√2 and then added the 2√5 but since they don't have the same square root we can't add them like we did in the other so we'll just put 7√2+2√5
Answer:
9y-y-7y+3= y+3
Step-by-step explanation:
Any time there is no number in front of a variable, it's automatically 1, you just don't put the 1 there. So it would be
9y - 1y= 8y
So after you do that, you take the 7y and subtract it from 8y
8y - 7y= 1y
And remember you don't put the 1 so it simplifies to just y.
You simply add or subtract all the numbers with the same variable
