Step-by-step explanation:

1). The expression 2 + 4 ÷ 2 = 3 is given while its simplification gives 4

Therefore, Option B. False is the correct option.

2). 17n + 2 is a numerical expression.

Option A. True

3). Variable expression for the phrase " Two more than x " would be (x + 2)

It's A. True

4). A verbal phrase for "6n - 4" is Option B. The difference of six times a number and four.

5).(7² - 9) ÷ (55 - 35)

= (49 - 9) ÷ (20)

= 40 ÷ 20

= 2

Option B is the answer.

6). Variable expression for the phrase " Two more than a number x would be (x - 2)

It should be (x + 2)

Therefore, B. False is the answer.

7). -5 + (-1) + 6 + 4

= -5 - 1 + 6 + 4

= 4

Option D. is the answer

8). " 18 more than 4 times a number"

Algebraic expression will be 4x + 18

Option B. is the answer.

9) 5( 11 + 2² - 10) - 19

= 5(11 + 4 - 10) - 19

= 5(15 - 10) - 19

= 5×5 - 19

= 25 - 19

= 6

Option B. is the answer.

10). -5 + 6 = 1

Option A. is the answer.

11). -5 + (-2) + 3 = -6 is given

-5 + (-2) + 3 = -7 + 3 = 4

Therefore, B. False is the answer.

12). (13² - 2²) ÷ 5

= (169 - 4) ÷ 5

= 165 ÷ 5

= 33

Option B. is the answer.

13).Opposite of 8 means opposite in sign notation

So Option D. -8 is the answer.
