B. (z + 5)(z + 5)
C. (z − 2)(z + 5)
D. (z + 2)(z − 5)
Solution-
As the question is not complete so contemplating all the possible scenarios,
1st - z² + 10z + 25
2nd - z² - 10z + 25
For,
And for,
So, the factored form of the polynomials are,
The factors of the equation z² - 10z + 25 are (z − 5)(z − 5).
Given Equation;
z² - 10z + 25
Splitting the middle term Using formula Using Quadratic formula Using algebraic identities.
The factors of the equation are;
z² - 10z + 25
z² -5z -5z + 25
z(z − 5) - 5(z − 5)
(z − 5)(z − 5)
Hence, the factors of the equation z² - 10z + 25 are (z − 5)(z − 5).

Answer:
The answer is 6.56
Step-by-step explanation:
11.20 is the total. You multiply that by .15 and get $1.68 for the tip. You multiply $11.20 by .05 for the tax and get $.56. You add them together and get $13.44. You subtract that from $20.00 and get $6.56
