Sherman goes golfing every 6^\text{th}6 th 6, start superscript, t, h, end superscript day and brad goes golfing every 7^\text{th}7 th 7, start superscript, t, h, end superscript day. if sherman and brad both went golfing today, how many days until they will go golfing on the same day again?

42 days

Step-by-step explanation:

To solve this problem one must find the Least Common Multiple (LCM) between the days it takes for both Sherman and Brad to go golfing (6 and 7)

Since 7 is a prime number the LCM, in this case, is the product of 7 by the other number:

It will be 42 days until Sherman and Brad will go golfing on the same day again.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
