Determine if the set of numbers create a Pythagorean triple. 2.1, 7.2, and 7.5

Yes, the set of numbers create a Pythagorean triple

Step-by-step explanation:

we know that

If a set of numbers create a Pythagorean triple, then the set of numbers must satisfy the Pythagorean Theorem

where

c is the greater side

a and b are the legs (perpendicular sides)

we have

substitute

----> is true

therefore

Yes, the set of numbers create a Pythagorean triple

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
