This set of 3 numbers are measurements of a right triangle. 26, 24, 10

True
False

True

Step-by-step explanation:

24^2 = 576

10^2 =100

576+100=676

26^2=676

True

Step-by-step explanation:

Use the pathagorean theorum:

a squared +b squared=c squared

(the numbers squared)

676, 576, 100

a=576 b=100 c=676

because 676=576+100

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,
