(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 20 represents the specific section, the 8 adds onto that side making the full side 8.
-> See attached
Using this, we can set up a proportion to solve;
<em>Sides of the smaller triangle are on the top, and sides of the larger triangle are on the bottom</em>
[Proportion we made]

[Cross-multiply]
20x = 140
[Divide both sides of the equation by 20]
x = 7 ✓
This is how they reached 7, I hope this answer explains it so you can understand.
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
