Answer:
for 
#1 is correct- The constant is 7
#2 is correct- The poly is in standard form
#3 is correct- the leading coefficient is 4
#4 is correct- there are 4 terms
Answer : 4x + 1 3/4 = 10
Step - by - step explanation : The reason 4 has an " x " at the end of it is because we don't know its exact number
<span>2x + 5 = 27
subtract 5 to both sides
2x + 5 - 5 = 27 - 5
simplify
2x = 22
divide both sides by 2
2x/2 = 22/2
simplify
x = 11
answer is </span><span>11 (second choice)
</span>

you lose 9 points because you went 3 times the limit
First, I'd like to say that this question is flawed because the diameter of the spool changes as you pull the line out. Some would argue it's negligible I suppose.
At any rate, assuming there's a magic spool where the diameter doesn't change, let's find the cicumference so we can find the length of one wrap around the spool.
circumference = 2*pi*r = 2 * pi * 4cm = about 25.133 cm
Now if it turns 16 times we'll have 16 times the circumference.
16 * (25.133 cm)
= 402.128 cm
