Answer:
hypotenuse = 10
Step-by-step explanation:
If you can tell at first glance it is a 3,4,5 triangle (6,8,10)/2=(3,4,5). Then you know that c has to equal 5.
If not,
a^2+b^2=c^2
6^2+8^2=c^2
36+64=c^2
100=c^2
10=c
Just like you round to the rearst whole number 4 and below gose down 5 and up gose up
Adding rational numbers involves adding decimals and repeating decimals like 4.6666666..... Whole numbers on the other hand involves adding 7+6 which arent exactly decimals
C=11/35
You subtract 4/35 from both sides.
I only know number 3.Number 3 is choice c/9 because you add all the numbers Carolina wrote.The divide the total by the number of numbers there are which is 5.So you would do 45÷5 which equals 9.
