Choose your favorite pythagorean triple (a, b, c) that has aa and bb sharing only 1 as a common factor, for example
(3, 4, 5), (5, 12, 13), or (7, 24, 25), … find the square of the length of a square root of a + bi; that is, find |p + qi|^2,
where p + qi is a square root of a + bi. what do you observe?

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

step-by-step explanation:

c

-by-step explanation:

it would be c
