The answer should be A. 4.5
Because line x is just over half of the length of the line that is 8ft
From multiplying the binomial expression
(n+3)(n-9)
It would be n^2 - 9n + 3n - 27 or simplified
n^2 -6n - 27.
Answer:
339.29 m³
Step-by-step explanation:
π · r² · h
π · 3² · 12
π · 9 · 12
π · 108
Reorder terms so constants are on the left
(3x + 7) 8x^2
8(3x +7)x^2
Distribute
Answer: 24x^3+56x^2
You didn't clarify what the angle is needed for, but still, I'd say never.
If you know two sides of a right triangle you can always find the third using the pythagorean theorem.
Once all sides are known, you can find the three angles: one is surely right, since you have a right triangle. The other two can be found using the sine law.
