Answer:

A Pythagorean triple consists of three positive integers a, b, and c, such that a² + b² = c². Such a triple is commonly written (a, b, c), and a well-known example is (3, 4, 5). If (a, b, c) is a Pythagorean triple, then so is (ka, kb, kc) for any positive integer k. A primitive Pythagorean triple is one in which a, b and c are coprime (that is, they have no common divisor larger than 1). A triangle whose sides form a Pythagorean triple is called a Pythagorean triangle, and is necessarily a right triangle.

Select all sets in which the number

strojnjashka [21]

Answer:

Step-by-step explanation:

a rational number can be expressed as fraction. well, that is what the number 8/9 is.

so, A is a correct option.

as such it is automatically also a member of the real numbers (which is a superset of rational numbers). so, E is a correct option.

all other options are wrong.

8/9 is not a natural number (1, 2, 3, 4, ...).

it is not a whole number (0, 1, 2, 3, 4, ...).

it is not an integer (... , -2, -1, 0, 1, 2, 3, ...).

and as it is a rational number, it is automatically not an irrational number.

Solve the quadratic formula (x+3)^2=69

mote1985 [20]

Answer:

Step-by-step explanation:

The given quadratic equation is expressed as

(x + 3)² = 69

(x + 3)(x + 3) = 69

x² + 3x + 3x = 69

x² + 6x - 69 = 0

The general formula for solving quadratic equations is expressed as

x = [- b ± √(b² - 4ac)]/2a

From the equation given,

a = 1

b = 6

c = - 69

Therefore,

x = [- 6 ± √(6² - 4 × 1 × - 69)]/2 × 1

x = [- 6 ± √(36 + 276)]/2

x = [- 6 ± √312]/2

x = (- 6 + 17.7)/2 or x = (- 6 - 17.7)/2

x = 11.7/2 or x = -23.7/2

x = 5.85 or x= - 11.85
