your answer is 5 bc you want to rearrange the numbers like this (5i - 5i) - (3 -(-2)) so (5i - 5i)= 0 and 3 - (-2) is 5
We need a picture. What are the answer choices
To get the difference we proceed as follows:
<span>3n^2(n^2+4n-5) - (2n^2-n^4+3)
open the parenthesis
3n</span>²×n²+3n²×4n-3n²×5-2n²+n⁴-3
this will give us:
3n⁴+12n³-15n²-2n²+n⁴-3
putting like terms together
3n⁴+n⁴+12n³-15n²-2n²-3
simplifying further we obtain
4n⁴+12n³-17n²-3
b] The highest degree of the the result will be obtained by considering the term with the highest power. The highest power is 4, thus the result will be classified as polynomial of degree 4.
Answer:
The solutions are 0° and 3π
Step-by-step explanation:
On solving the equation given;
<u>Since sin is negative in the 3rd and 4th quadrant, </u>
In the 3rd quadrant;
x =180°+2π
x = π + 2π
x = 3π
In the 4th quadrant;
x = 360°-2π
x = 2π-2π
x = 0°
