<h3>
Answer: perimeter = 10+2x+xy</h3>
To get the perimeter, you add up all the outer sides
side1+side2+side3 = (5+x)+(5+x)+(xy) = 10+2x+xy
The like terms 5 and 5 add to 10. The other pair of like terms x and x add to 2x. There isn't anything to pair with xy, so we leave it as is.

Step-by-step explanation:
The expression to find the number of notebooks James bought would be written as:
Number of notebooks = total spent / cost per item
Number of notebooks = (2y^2 + 6) / <span>(y^2 − 1)
</span><span>If y = 3, then the number of notebooks bought would be:
</span>Number of notebooks = (2y^2 + 6) / (y^2 − 1)
Number of notebooks = (2(3)^2 + 6) / (3^2 − 1)
Number of notebooks = 3 pieces<span>

Ms D left at 6:40 AM
Step-by-step explanation:
Given:
MS D arrived at school at 7:30 AM
time spent for dinner = 35 mins
Time taken to to go to school = 15 mins
We will first find the Total time taken after leaving.
Total time taken can be calculated by adding time spent for dinner and Time taken to to go to school.
Total time taken after leaving = time spent for dinner + Time taken to to go to school = 35 +15 = 50 mins
MS D arrived at school at 7:30 AM.
Hence Time Ms D left = Time She arrive at school - Total time taken after leaving = 7 hrs 30 min - 50 mins = 6 hrs 40 mins.
Hence Ms D left at 6:40 AM.
