Answer: -16n-41

Step-by-step explanation:

first, distribute 2 through the parentheses:

<u>2(-n-3)</u>-7(5+2n) = <u>-2n-6</u>-7(5+2n)

second, distribute 7 through the parenthesis:

-2n-6<u>-7(5+2n) </u>= -2n-6<u>-35-14n</u>

Collect like terms:

<u>-2n</u>-6-35 and <u>-16n</u>-6-35

Calculate the difference:

-2n<u>-6-35</u>-14n = -16n-<u>41</u>

SOLUTION:

<u>-16n-41</u>

Evaluate and simplify the expression when a = 3 and b = 2. 3b-2(1 - b) a - 2 II [ ? ] Enter Copyright © 2003.2010​
tatuchka [14]

Correct question:

Evaluate and simplify the expression when a = 3 and b = 2,

given expression =  3b-2(1 - b)a - 2

Answer:

3b-2(1 - b)a - 2 at the given values is 10.

Step-by-step explanation:

Given;

3b-2(1 - b)a - 2

The expression is simplified as;

3b-2(1 - b) a - 2 = 3b - 2a(1 - b) - 2

                         = 3b - 2a + 2ab - 2

When a = 3 and b = 2; then, substitute these values in the simplified expression above;

3b - 2a + 2ab - 2 = 3(2) - 2(3) + 2(3 x 2) - 2

                            = 6 - 6 + 12 - 2

                            = 10

Therefore, 3b-2(1 - b)a - 2 at the given values is 10.
