Answer:
Choice C.
Step-by-step explanation:
3rd degree means that the expression must have power of 3 as the highest power.
So, choice b is wrong since it has highest power of 8. All the other choices have highest power of 3.
Binomial means expression that has two terms.
So, choices d and a are wrong because they have 3 terms each.
So, choice C is correct answer and also it has constant as 8.

Answer:
−1.13348172≤x≤1.13348172
Step-by-step explanation:
For this problem
Add −5x2 to both sides of the inequality.
−x16 + 1 + 5x2≥0
Convert inequality to an equation.
−x16 + 1 + 5x2 = 0
Factor −x16 + 1 + 5x2
Set the factor equal to 00.
x16−5x2−1 = 0
x≈ − 1.13348172,1.13348172
so,
x≤ − 1,13348172
−1.13348172≤x≤1.13348172
x≥1.13348172
−1.13348172≤x≤1.13348172
What we know:
Lot= 21 x 30ft
Perimeter=2l+2w
Want to put 4 corner post and one post every 3 ft
What we need to find:
How many post we need.
Perimeter=2 (21)+2 (30)=42+60=102ft
102/3=34
34 posts are needed.
The slope is negative one
