Answer 1

Step-by-step explanation:

289/9 - 2 X 5 X 2/3

289/9 - 20/3

229/9 is the answer and all options are wrong..

Answer 2

Answer:

• (x - 5)² = (x - 5)(x - 5)

(x - 5)² = (x - 5)(x - 5)Using the Distributive Property, we get:

• (x - 5)² = (x - 5)(x - 5)Using the Distributive Property, we get:= x(x - 5) - 5(x - 5)

• (x - 5)² = (x - 5)(x - 5)Using the Distributive Property, we get:= x(x - 5) - 5(x - 5)= x(x) - x(5) + [-5(x - 5)]

• (x - 5)² = (x - 5)(x - 5)Using the Distributive Property, we get:= x(x - 5) - 5(x - 5)= x(x) - x(5) + [-5(x - 5)]= x(x) - x(5) + (-5)(x) - (-5)(5)

• (x - 5)² = (x - 5)(x - 5)Using the Distributive Property, we get:= x(x - 5) - 5(x - 5)= x(x) - x(5) + [-5(x - 5)]= x(x) - x(5) + (-5)(x) - (-5)(5)= x² - 5x + (-5x) - (-25)

• (x - 5)² = (x - 5)(x - 5)Using the Distributive Property, we get:= x(x - 5) - 5(x - 5)= x(x) - x(5) + [-5(x - 5)]= x(x) - x(5) + (-5)(x) - (-5)(5)= x² - 5x + (-5x) - (-25)= x² - 5x - 5x + 25

(x - 5)² = (x - 5)(x - 5)Using the Distributive Property, we get:= x(x - 5) - 5(x - 5)= x(x) - x(5) + [-5(x - 5)]= x(x) - x(5) + (-5)(x) - (-5)(5)= x² - 5x + (-5x) - (-25)= x² - 5x - 5x + 25Collecting like-terms, the final result (product) is:

• (x - 5)² = (x - 5)(x - 5)Using the Distributive Property, we get:= x(x - 5) - 5(x - 5)= x(x) - x(5) + [-5(x - 5)]= x(x) - x(5) + (-5)(x) - (-5)(5)= x² - 5x + (-5x) - (-25)= x² - 5x - 5x + 25Collecting like-terms, the final result (product) is:= x² - 10x + 25 is the quadratic trinomial that you get when you square the linear binomial (x - 5).
