Braces, also called curly brackets in used to list the elements of a set in a roster notation.
While parenthesis is used in interval notation.
Step-by-step explanation:
x=1.25y
perimeter= 2width+2length
olivias p=ryan's p so:
Ryan's p= 2*1.25 Ryan's width+ 2Olivias length
Olivias length= (2,5Ryan's width- Ryan's p)/2
X is the hypotenuse of an isosceles triangle. The length of the sides are the difference of the inner and outer squares divided by 2. Which means that the sides of the triangle is 1.5 inches. Using that information, the length of X can be deduced to be 2.12 inches using Pythagoras theorem
