Which expression represents the sum (3z−11)+(6−6z) ?

The expression which represents the sum (3z−11)+(6−6z) is; -3z -5

According to the question;

Evidently, the expression above is a one-variable expresssion.

As such, the sum can be evaluated by outright addition of like terms as follows;

(3z−11)+(6−6z).

= 3z + (-6z) -11 + 6.

= -3z - 5.

Step-by-step explanation:

(3z−11)+(6−6z)

3z - 11 + 6 - 6z

- 6z + 3z - 11 + 6

- 3z - 5

z = -5/-3

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
