What are the answers to these problems

(1) Option B: –10

(2) Option A: –3

Solution:

(1) Given expression is 37 + n.

To evaluate the value of the expression when n = –47.

Substitute n = –47 in the given expression.

37 + n = 37 + (–47)

Since positive of a negative number is negative.

37 + n = 37 – 47

Subtract 37 from 47 and put the greater number sign for the answer.

37 + n = –10

Option B is the correct answer.

Hence 37 + n = –10.

(2) Given expression is p – q.

To find the the value of the expression when p = –37 and q = –34

p – q = (–37) – (–34)

Since negative of a negative number is positive.

p – q = (–37) + 34

Subtract 34 from 37 and put the greater number sign for the answer.

p – q = –3

Option A is the correct answer.

Hence p – q = –3.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
